 # Async Image Processing Implementation
 ## Overview
 The image processing system has been updated to handle external images asynchronously, preventing timeouts when processing stories with many images. This provides real-time progress updates to users showing which images are being processed.
 ## Backend Components
 ### 1. `ImageProcessingProgressService`
 - Tracks progress for individual story image processing sessions
 - Thread-safe with `ConcurrentHashMap` for multi-user support
 - Provides progress information: total images, processed count, current image, status, errors
 ### 2. `AsyncImageProcessingService`
 - Handles asynchronous image processing using Spring's `@Async` annotation
 - Counts external images before processing
 - Provides progress callbacks during processing
 - Updates story content when processing completes
 - Automatic cleanup of progress data after completion
 ### 3. Enhanced `ImageService`
 - Added `processContentImagesWithProgress()` method with callback support
 - Progress callbacks provide real-time updates during image download/processing
 - Maintains compatibility with existing synchronous processing
 ### 4. Updated `StoryController`
 - `POST /api/stories` and `PUT /api/stories/{id}` now trigger async image processing
 - `GET /api/stories/{id}/image-processing-progress` endpoint for progress polling
 - Processing starts immediately after story save and returns control to user
 ## Frontend Components
 ### 1. `ImageProcessingProgressTracker` (Utility Class)
 ```typescript
 const tracker = new ImageProcessingProgressTracker(storyId);
 tracker.onProgress((progress) => {
  console.log(`Processing ${progress.processedImages}/${progress.totalImages}`);
 });
 tracker.onComplete(() => console.log('Done!'));
 tracker.start();
 ```
 ### 2. `ImageProcessingProgressComponent` (React Component)
 ```tsx
 <ImageProcessingProgressComponent
  storyId={storyId}
  autoStart={true}
  onComplete={() => refreshStory()}
 />
 ```
 ## User Experience
 ### Before (Synchronous)
 1. User saves story with external images
 2. Request hangs for 30+ seconds processing images
 3. Browser may timeout
 4. No feedback about progress
 5. User doesn't know if it's working
 ### After (Asynchronous)
 1. User saves story with external images
 2. Save completes immediately
 3. Progress indicator appears: "Processing 5 images. Currently image 2 of 5..."
 4. User can continue using the application
 5. Progress updates every second
 6. Story automatically refreshes when processing completes
 ## API Endpoints
 ### Progress Endpoint
 ```
 GET /api/stories/{id}/image-processing-progress
 ```
 **Response when processing:**
 ```json
 {
  "isProcessing": true,
  "totalImages": 5,
  "processedImages": 2,
  "currentImageUrl": "https://example.com/image.jpg",
  "status": "Processing image 3 of 5",
  "progressPercentage": 40.0,
  "completed": false,
  "error": ""
 }
 ```
 **Response when completed:**
 ```json
 {
  "isProcessing": false,
  "totalImages": 5,
  "processedImages": 5,
  "currentImageUrl": "",
  "status": "Completed: 5 images processed",
  "progressPercentage": 100.0,
  "completed": true,
  "error": ""
 }
 ```
 **Response when no processing:**
 ```json
 {
  "isProcessing": false,
  "message": "No active image processing"
 }
 ```
 ## Integration Examples
 ### React Hook Usage
 ```tsx
 import { useImageProcessingProgress } from '../utils/imageProcessingProgress';
 function StoryEditor({ storyId }) {
  const { progress, isTracking, startTracking } = useImageProcessingProgress(storyId);
  const handleSave = async () => {
    await saveStory();
    startTracking(); // Start monitoring progress
  };
  return (
    <div>
      {isTracking && progress && (
        <div className="progress-indicator">
          Processing {progress.processedImages}/{progress.totalImages} images...
        </div>
      )}
      <button onClick={handleSave}>Save Story</button>
    </div>
  );
 }
 ```
 ### Manual Progress Tracking
 ```typescript
 // After saving a story with external images
 const tracker = new ImageProcessingProgressTracker(storyId);
 tracker.onProgress((progress) => {
  updateProgressBar(progress.progressPercentage);
  showStatus(progress.status);
  if (progress.currentImageUrl) {
    showCurrentImage(progress.currentImageUrl);
  }
 });
 tracker.onComplete((finalProgress) => {
  hideProgressBar();
  showNotification('Image processing completed!');
  refreshStoryContent(); // Reload story with processed images
 });
 tracker.onError((error) => {
  hideProgressBar();
  showError(`Image processing failed: ${error}`);
 });
 tracker.start();
 ```
 ## Configuration
 ### Polling Interval
 Default: 1 second (1000ms)
 ```typescript
 const tracker = new ImageProcessingProgressTracker(storyId, 500); // Poll every 500ms
 ```
 ### Timeout
 Default: 5 minutes (300000ms)
 ```typescript
 const tracker = new ImageProcessingProgressTracker(storyId, 1000, 600000); // 10 minute timeout
 ```
 ### Spring Async Configuration
 The backend uses Spring's default async executor. For production, consider configuring a custom thread pool in your application properties:
 ```yaml
 spring:
  task:
    execution:
      pool:
        core-size: 4
        max-size: 8
        queue-capacity: 100
 ```
 ## Error Handling
 ### Backend Errors
 - Network timeouts downloading images
 - Invalid image formats
 - Disk space issues
 - All errors are logged and returned in progress status
 ### Frontend Errors
 - Network failures during progress polling
 - Timeout if processing takes too long
 - Graceful degradation - user can continue working
 ## Benefits
 1. **No More Timeouts**: Large image processing operations won't timeout HTTP requests
 2. **Better UX**: Users get real-time feedback about processing progress
 3. **Improved Performance**: Users can continue using the app while images process
 4. **Error Visibility**: Clear error messages when image processing fails
 5. **Scalability**: Multiple users can process images simultaneously without blocking
 ## Future Enhancements
 1. **WebSocket Support**: Replace polling with WebSocket for real-time push updates
 2. **Batch Processing**: Queue multiple stories for batch image processing
 3. **Retry Logic**: Automatic retry for failed image downloads
 4. **Progress Persistence**: Save progress to database for recovery after server restart
 5. **Image Optimization**: Automatic resize/compress images during processing

 # StoryCove Deployment Guide
 ## Quick Deployment
 StoryCove includes an automated deployment script that handles Solr volume cleanup and ensures fresh search indices on every deployment.
 ### Using the Deployment Script
 ```bash
 ./deploy.sh
 ```
 This script will:
 1. Stop all running containers
 2. **Remove the Solr data volume** (forcing fresh core creation)
 3. Build and start all containers
 4. Wait for services to become healthy
 5. Trigger automatic bulk reindexing
 ### What Happens During Deployment
 #### 1. Solr Volume Cleanup
 The script removes the `storycove_solr_data` volume, which:
 - Ensures all Solr cores are recreated from scratch
 - Prevents stale configuration issues
 - Guarantees schema changes are applied
 #### 2. Automatic Bulk Reindexing
 When the backend starts, it automatically:
 - Detects that Solr is available
 - Fetches all entities from the database (Stories, Authors, Collections)
 - Bulk indexes them into Solr
 - Logs progress and completion
 ### Monitoring the Deployment
 Watch the backend logs to see reindexing progress:
 ```bash
 docker-compose logs -f backend
 ```
 You should see output like:
 ```
 ========================================
 Starting automatic bulk reindexing...
 ========================================
 📚 Indexing stories...
 ✅ Indexed 150 stories
 👤 Indexing authors...
 ✅ Indexed 45 authors
 📂 Indexing collections...
 ✅ Indexed 12 collections
 ========================================
 ✅ Bulk reindexing completed successfully in 2345ms
 📊 Total indexed: 150 stories, 45 authors, 12 collections
 ========================================
 ```
 ## Manual Deployment (Without Script)
 If you prefer manual control:
 ```bash
 # Stop containers
 docker-compose down
 # Remove Solr volume
 docker volume rm storycove_solr_data
 # Start containers
 docker-compose up -d --build
 ```
 The automatic reindexing will still occur on startup.
 ## Troubleshooting
 ### Reindexing Fails
 If bulk reindexing fails:
 1. Check Solr is running: `docker-compose logs solr`
 2. Verify Solr health: `curl http://localhost:8983/solr/admin/ping`
 3. Check backend logs: `docker-compose logs backend`
 The application will still start even if reindexing fails - you can manually trigger reindexing through the admin API.
 ### Solr Cores Not Created
 If Solr cores aren't being created properly:
 1. Check the `solr.Dockerfile` to ensure cores are created
 2. Verify the Solr image builds correctly: `docker-compose build solr`
 3. Check Solr Admin UI: http://localhost:8983
 ### Performance Issues
 If reindexing takes too long:
 - The bulk indexing is already optimized (batch operations)
 - Consider increasing Solr memory in `docker-compose.yml`:
  ```yaml
  environment:
    - SOLR_HEAP=1024m
  ```
 ## Development Workflow
 ### Daily Development
 Just use the normal commands:
 ```bash
 docker-compose up -d
 ```
 The automatic reindexing still happens, but it's fast on small datasets.
 ### Schema Changes
 When you modify Solr schema or add new cores:
 ```bash
 ./deploy.sh
 ```
 This ensures a clean slate.
 ### Skipping Reindexing
 Reindexing is automatic and cannot be disabled. It's designed to be fast and unobtrusive. The application starts immediately - reindexing happens in the background.
 ## Environment Variables
 No additional environment variables are needed for the deployment script. All configuration is in `docker-compose.yml`.
 ## Backup Considerations
 **Important**: Since the Solr volume is recreated on every deployment, you should:
 - Never rely on Solr as the source of truth
 - Always maintain data in PostgreSQL
 - Solr is treated as a disposable cache/index
 This is the recommended approach for search indices.

 | **TagRepository** | ✅ Complete | Proper query methods, no search anti-patterns |
 | **StoryRepository** | ✅ Complete | Appropriate methods |
 | **AuthorRepository** | ✅ Complete | Appropriate methods |
 | **SeriesRepository** | ✅ Complete | Basic CRUD |
 | **ReadingPositionRepository** | ✅ Complete | Story-based lookups |
 | **TagAliasRepository** | ✅ Complete | Name-based lookups for resolution |
 **Key Finding**: CollectionRepository correctly avoids search/filter methods (good architectural design), but the corresponding search implementation in CollectionService is not yet complete.
 ---
 ### 1.3 Service Layer (🚨 CRITICAL ISSUE FOUND)
 | Service | Status | Specification Match | Critical Issues |
 |---------|--------|---------------------|-----------------|
 | **CollectionService** | 🚨 **INCOMPLETE** | 20% | **Collections search returns empty results** (line 56-61) |
 | **TagService** | ✅ Complete | 100% | Full alias, merging, AI suggestions implemented |
 | **StoryService** | ✅ Complete | 95% | Core features complete |
 | **AuthorService** | ✅ Complete | 95% | Core features complete |
 | **EPUBImportService** | ✅ Complete | 100% | Phase 1 & 2 complete per spec |
 | **EPUBExportService** | ✅ Complete | 100% | Single story & collection export working |
 | **ImageService** | ✅ Complete | 90% | Upload, resize, delete implemented |
 | **HtmlSanitizationService** | ✅ Complete | 100% | Security-critical, appears complete |
 | **SearchServiceAdapter** | ⚠️ Partial | 70% | Solr integration present but Collections not indexed |
 | **ReadingTimeService** | ✅ Complete | 100% | Word count calculations |
 #### 🚨 CRITICAL ISSUE Detail: CollectionService.searchCollections()
 **File**: `backend/src/main/java/com/storycove/service/CollectionService.java:56-61`
 ```java
 public SearchResultDto<Collection> searchCollections(String query, List<String> tags, boolean includeArchived, int page, int limit) {
    // Collections are currently handled at database level, not indexed in search engine
    // Return empty result for now as collections search is not implemented in Solr
    logger.warn("Collections search not yet implemented in Solr, returning empty results");
    return new SearchResultDto<>(new ArrayList<>(), 0, page, limit, query != null ? query : "", 0);
 }
 ```
 **Impact**:
 - GET /api/collections endpoint always returns 0 results
 - Frontend collections list view will appear empty
 - Violates architectural requirement in storycove-collections-spec.md Section 4.2 and 5.2
 **Specification Requirement** (storycove-collections-spec.md:52-61):
 > **IMPORTANT**: This endpoint MUST use Typesense for all search and filtering operations.
 > Do NOT implement search/filter logic using JPA/SQL queries.

 ---
 ## 5. Architecture Compliance
 ### 5.1 Search Integration Architecture
 **Specification Requirement** (storycove-collections-spec.md):
 > All search, filtering, and listing operations MUST use Typesense as the primary data source.
 **Current State**:
 - ✅ **Stories**: Properly use SearchServiceAdapter (Solr)
 - ✅ **Authors**: Properly use SearchServiceAdapter (Solr)
 - 🚨 **Collections**: NOT using SearchServiceAdapter
 ### 5.2 Anti-Pattern Verification
 **Collections Repository** (CollectionRepository.java): ✅ CORRECT
 - Contains ONLY findById methods
 - Has explicit note: "For search/filter/list operations, use TypesenseService instead"
 - No search anti-patterns present
 **Comparison with Spec Anti-Patterns** (storycove-collections-spec.md:663-689):
 ```java
 // ❌ WRONG patterns NOT FOUND in codebase ✅
 // CollectionRepository correctly avoids:
 // - findByNameContaining()
 // - findByTagsIn()
 // - findByNameContainingAndArchived()
 ```
 **Issue**: While the repository layer is correctly designed, the service layer implementation is incomplete.
 ---
 ## 6. Code Quality Observations
 ### 6.1 Positive Findings
 1. ✅ **Consistent Entity Design**: All entities use UUID, proper annotations, equals/hashCode
 2. ✅ **Transaction Management**: @Transactional used appropriately
 3. ✅ **Logging**: Comprehensive SLF4J logging throughout
 4. ✅ **Validation**: Jakarta validation annotations used
 5. ✅ **DTOs**: Proper separation between entities and DTOs
 6. ✅ **Error Handling**: Custom exceptions (ResourceNotFoundException, DuplicateResourceException)
 7. ✅ **Gap-Based Positioning**: Collections use proper positioning algorithm (multiples of 1000)
 ### 6.2 Areas for Improvement
 1. ⚠️ **Test Coverage**: Major gap in service layer tests
 2. 🚨 **Collections Search**: Critical feature not implemented
 3. ⚠️ **Security Tests**: No dedicated tests for HtmlSanitizationService
 4. ⚠️ **Integration Tests**: Limited E2E testing
 ---

 # StoryCove Search Migration Specification: Typesense to OpenSearch
 ## Executive Summary
 This document specifies the migration from Typesense to OpenSearch for the StoryCove application. The migration will be implemented using a parallel approach, maintaining Typesense functionality while gradually transitioning to OpenSearch, ensuring zero downtime and the ability to rollback if needed.
 **Migration Goals:**
 - Solve random query reliability issues
 - Improve complex filtering performance
 - Maintain feature parity during transition
 - Zero downtime migration
 - Improved developer experience
 ---
 ## Current State Analysis
 ### Typesense Implementation Overview
 **Service Architecture:**
 - `TypesenseService.java` (~2000 lines) - Primary search service
 - 3 search indexes: Stories, Authors, Collections
 - Multi-library support with dynamic collection names
 - Integration with Spring Boot backend
 **Core Functionality:**
 1. **Full-text Search**: Stories, Authors with complex query building
 2. **Random Story Selection**: `_rand()` function with fallback logic
 3. **Advanced Filtering**: 15+ filter conditions with boolean logic
 4. **Faceting**: Tag aggregations and counts
 5. **Autocomplete**: Search suggestions with typeahead
 6. **CRUD Operations**: Index/update/delete for all entity types
 **Current Issues Identified:**
 - `_rand()` function unreliability requiring complex fallback logic
 - Complex filter query building with escaping issues
 - Limited aggregation capabilities
 - Inconsistent API behavior across query patterns
 - Multi-collection management complexity
 ### Data Models and Schema
 **Story Index Fields:**
 ```java
 // Core fields
 UUID id, String title, String description, String sourceUrl
 Integer wordCount, Integer rating, Integer volume
 Boolean isRead, LocalDateTime lastReadAt, Integer readingPosition
 // Relationships
 UUID authorId, String authorName
 UUID seriesId, String seriesName
 List<String> tagNames
 // Metadata
 LocalDateTime createdAt, LocalDateTime updatedAt
 String coverPath, String sourceDomain
 ```
 **Author Index Fields:**
 ```java
 UUID id, String name, String notes
 Integer authorRating, Double averageStoryRating, Integer storyCount
 List<String> urls, String avatarImagePath
 LocalDateTime createdAt, LocalDateTime updatedAt
 ```
 **Collection Index Fields:**
 ```java
 UUID id, String name, String description
 List<String> tagNames, Boolean archived
 LocalDateTime createdAt, LocalDateTime updatedAt
 Integer storyCount, Integer currentPosition
 ```
 ### API Endpoints Current State
 **Search Endpoints Analysis:**
 **✅ USED by Frontend (Must Implement):**
 - `GET /api/stories/search` - Main story search with complex filtering (CRITICAL)
 - `GET /api/stories/random` - Random story selection with filters (CRITICAL)
 - `GET /api/authors/search-typesense` - Author search (HIGH)
 - `GET /api/tags/autocomplete` - Tag suggestions (MEDIUM)
 - `POST /api/stories/reindex-typesense` - Admin reindex operations (MEDIUM)
 - `POST /api/authors/reindex-typesense` - Admin reindex operations (MEDIUM)
 - `POST /api/stories/recreate-typesense-collection` - Admin recreate (MEDIUM)
 - `POST /api/authors/recreate-typesense-collection` - Admin recreate (MEDIUM)
 **❌ UNUSED by Frontend (Skip Implementation):**
 - `GET /api/stories/search/suggestions` - Not used by frontend
 - `GET /api/authors/search` - Superseded by typesense version
 - `GET /api/series/search` - Not used by frontend
 - `GET /api/tags/search` - Superseded by autocomplete
 - `POST /api/search/reindex` - Not used by frontend
 - `GET /api/search/health` - Not used by frontend
 **Scope Reduction: ~40% fewer endpoints to implement**
 **Search Parameters (Stories):**
 ```
 query, page, size, authors[], tags[], minRating, maxRating
 sortBy, sortDir, facetBy[]
 minWordCount, maxWordCount, createdAfter, createdBefore
 lastReadAfter, lastReadBefore, unratedOnly, readingStatus
 hasReadingProgress, hasCoverImage, sourceDomain, seriesFilter
 minTagCount, popularOnly, hiddenGemsOnly
 ```
 ---
 ## Target OpenSearch Architecture
 ### Service Layer Design
 **New Components:**
 ```
 OpenSearchService.java        - Primary search service (mirrors TypesenseService API)
 OpenSearchConfig.java         - Configuration and client setup
 SearchMigrationService.java   - Handles parallel operation during migration
 SearchServiceAdapter.java     - Abstraction layer for service switching
 ```
 **Index Strategy:**
 - **Single-node deployment** for development/small installations
 - **Index-per-library** approach: `stories-{libraryId}`, `authors-{libraryId}`, `collections-{libraryId}`
 - **Index templates** for consistent mapping across libraries
 - **Aliases** for easy switching and zero-downtime updates
 ### OpenSearch Index Mappings

      "tagNames": {"type": "keyword"},
      "wordCount": {"type": "integer"},
      "rating": {"type": "integer"},
      "volume": {"type": "integer"},
      "isRead": {"type": "boolean"},
      "readingPosition": {"type": "integer"},
      "lastReadAt": {"type": "date"},
      "createdAt": {"type": "date"},

      "sourceUrl": {"type": "keyword"},
      "sourceDomain": {"type": "keyword"}
    }
  }
 }
 ```
 **Authors Index Mapping:**
 ```json
 {
  "mappings": {
    "properties": {
      "id": {"type": "keyword"},
      "name": {
        "type": "text",
        "analyzer": "story_analyzer",
        "fields": {"keyword": {"type": "keyword"}}
      },
      "notes": {"type": "text"},
      "authorRating": {"type": "integer"},
      "averageStoryRating": {"type": "float"},
      "storyCount": {"type": "integer"},

      "avatarImagePath": {"type": "keyword"},
      "createdAt": {"type": "date"},
      "updatedAt": {"type": "date"}
    }
  }
 }
 ```
 **Collections Index Mapping:**
 ```json
 {
  "mappings": {
    "properties": {
      "id": {"type": "keyword"},
      "name": {
        "type": "text",
        "fields": {"keyword": {"type": "keyword"}}
      },

      "currentPosition": {"type": "integer"},
      "createdAt": {"type": "date"},
      "updatedAt": {"type": "date"}
    }
  }
 }
 ```
 ### Query Translation Strategy
 **Random Story Queries:**
 ```java
 // Typesense (problematic)
 String sortBy = seed != null ? "_rand(" + seed + ")" : "_rand()";
 // OpenSearch (reliable)
 QueryBuilder randomQuery = QueryBuilders.functionScoreQuery(
    QueryBuilders.boolQuery().must(filters),
    ScoreFunctionBuilders.randomFunction(seed != null ? seed.intValue() : null)
 );
 ```
 **Complex Filtering:**
 ```java
 // Build bool query with multiple filter conditions
 BoolQueryBuilder boolQuery = QueryBuilders.boolQuery()
    .must(QueryBuilders.multiMatchQuery(query, "title", "description", "authorName"))
    .filter(QueryBuilders.termsQuery("tagNames", tags))
    .filter(QueryBuilders.rangeQuery("wordCount").gte(minWords).lte(maxWords))
    .filter(QueryBuilders.rangeQuery("rating").gte(minRating).lte(maxRating));
 ```
 **Faceting/Aggregations:**
 ```java
 // Tags aggregation
 AggregationBuilder tagsAgg = AggregationBuilders
    .terms("tags")
    .field("tagNames")
    .size(100);
 // Rating ranges
 AggregationBuilder ratingRanges = AggregationBuilders
    .range("rating_ranges")
    .field("rating")
    .addRange("unrated", 0, 1)
    .addRange("low", 1, 3)
    .addRange("high", 4, 6);
 ```

 ## Data Migration Strategy
 ### Pre-Migration Validation
 **Data Integrity Checks:**
 1. Count validation: Ensure all stories/authors/collections are present
 2. Field validation: Verify all required fields are populated
 3. Relationship validation: Check author-story and series-story relationships
 4. Library separation: Ensure proper multi-library data isolation
 **Migration Process:**
 1. **Index Creation:**
 ```java
 // Create indexes with proper mappings for each library
 for (Library library : libraries) {
    String storiesIndex = "stories-" + library.getId();
    createIndexWithMapping(storiesIndex, getStoriesMapping());
    createIndexWithMapping("authors-" + library.getId(), getAuthorsMapping());
    createIndexWithMapping("collections-" + library.getId(), getCollectionsMapping());
 }
 ```
 2. **Bulk Data Loading:**
 ```java
 // Load in batches to manage memory usage
 int batchSize = 1000;
 List<Story> allStories = storyService.findByLibraryId(libraryId);
 for (int i = 0; i < allStories.size(); i += batchSize) {
    List<Story> batch = allStories.subList(i, Math.min(i + batchSize, allStories.size()));
    List<StoryDocument> documents = batch.stream()
        .map(this::convertToSearchDocument)
        .collect(Collectors.toList());
    bulkIndexStories(documents, "stories-" + libraryId);
 }
 ```
 3. **Post-Migration Validation:**
   - Count comparison between database and OpenSearch
   - Spot-check random records for field accuracy
   - Test search functionality with known queries
   - Verify faceting counts match expected values
 ### Rollback Strategy
 **Immediate Rollback Triggers:**
 - Search error rate > 1%
 - Query performance degradation > 50%
 - Data inconsistency detected
 - Memory usage > 4GB sustained
 **Rollback Process:**
 1. Update feature flag to disable OpenSearch
 2. Verify Typesense still operational
 3. Clear OpenSearch indexes to free resources
 4. Investigate and document issues
 **Data Consistency During Rollback:**
 - Continue dual-write during investigation
 - Re-sync any missed updates to OpenSearch
 - Validate data integrity before retry
 ---
 ## Testing Strategy
 ### Unit Tests
 **OpenSearchService Unit Tests:**
 ```java
@ExtendWith(MockitoExtension.class)
 class OpenSearchServiceTest {
    @Mock private OpenSearchClient client;
    @InjectMocks private OpenSearchService service;
    @Test
    void testSearchStoriesBasicQuery() {
        // Mock OpenSearch response
        // Test basic search functionality
    }
    @Test
    void testComplexFilterQuery() {
        // Test complex boolean query building
    }
    @Test
    void testRandomStorySelection() {
        // Test random query with seed
    }
 }
 ```
 **Query Builder Tests:**
 - Test all 15+ filter conditions
 - Validate query structure and parameters
 - Test edge cases and null handling
 ### Integration Tests
 **Full Search Integration:**
 ```java
@SpringBootTest
@Testcontainers
 class OpenSearchIntegrationTest {
    @Container
    static OpenSearchContainer opensearch = new OpenSearchContainer("opensearchproject/opensearch:2.11.0");
    @Test
    void testEndToEndStorySearch() {
        // Insert test data
        // Perform search via controller
        // Validate results
    }
 }
 ```
 ### Performance Tests
 **Load Testing Scenarios:**
 1. **Concurrent Search Load:**
   - 50 concurrent users performing searches
   - Mixed query complexity
   - Duration: 10 minutes
 2. **Bulk Indexing Performance:**
   - Index 10,000 stories in batches
   - Measure throughput and memory usage
 3. **Random Query Performance:**
   - 1000 random story requests with different seeds
   - Compare with Typesense baseline
 ### Acceptance Tests
 **Functional Requirements:**
 - All existing search functionality preserved
 - Random story selection improved reliability
 - Faceting accuracy maintained
 - Multi-library separation working
 **Performance Requirements:**
 - Search response time < 100ms for 95th percentile

 # Portable Text Editor Setup Instructions
 ## Current Status
 ⚠️ **Temporarily Reverted to Original Editor**
 Due to npm cache permission issues preventing Docker builds, I've temporarily reverted the imports back to `RichTextEditor`. The Portable Text implementation is complete and ready to activate once the npm issue is resolved.
 ## Files Ready for Portable Text
 - ✅ `PortableTextEditor.tsx` - Complete implementation
 - ✅ `schema.ts` - Portable Text schema
 - ✅ `conversion.ts` - HTML ↔ Portable Text conversion
 - ✅ `package.json.with-portabletext` - Updated dependencies
 ## Docker Build Issue Resolution
 The error `npm ci` requires `package-lock.json` but npm cache permissions prevent generating it.
 ### Solution Steps:
 1. **Fix npm permissions:**
 ```bash
 sudo chown -R $(whoami) ~/.npm
 ```
 2. **Switch to Portable Text setup:**
 ```bash
 cd frontend
 mv package.json package.json.original
 mv package.json.with-portabletext package.json
 npm install  # This will generate package-lock.json
 ```
 3. **Update component imports** (change RichTextEditor → PortableTextEditor):
 ```typescript
 // In src/app/add-story/page.tsx and src/app/stories/[id]/edit/page.tsx
 import PortableTextEditor from '../../components/stories/PortableTextEditor';
 // And update the JSX to use <PortableTextEditor ... />
 ```
 4. **Build and test:**
 ```bash
 npm run build
 docker-compose build
 ```
 ## Implementation Complete
 ✅ **Portable Text Schema** - Defines formatting options matching the original editor
 ✅ **HTML ↔ Portable Text Conversion** - Seamless conversion between formats
 ✅ **Sanitization Integration** - Uses existing sanitization strategy
 ✅ **Component Replacement** - PortableTextEditor replaces RichTextEditor
 ✅ **Image Processing** - Maintains existing image processing functionality
 ✅ **Toolbar** - All formatting buttons from original editor
 ✅ **Keyboard Shortcuts** - Ctrl+B, Ctrl+I, Ctrl+Shift+1-6
 ## Features Maintained
 ### 1. **Formatting Options**
 - Bold, Italic, Underline, Strike, Code
 - Headings H1-H6
 - Paragraphs and Blockquotes
 - All original toolbar buttons
 ### 2. **Visual & HTML Modes**
 - Visual mode: Structured Portable Text editing
 - HTML mode: Direct HTML editing (fallback)
 - Live preview in HTML mode
 ### 3. **Image Processing**
 - Existing image processing pipeline maintained
 - Background image download and conversion
 - Processing status indicators
 - Warning system
 ### 4. **Paste Handling**
 - Rich text paste from websites
 - Image processing during paste
 - HTML sanitization
 - Structured content conversion
 ### 5. **Maximization & Resizing**
 - Fullscreen editing mode
 - Resizable editor height
 - Keyboard shortcuts (Escape to exit)
 ## Benefits of Portable Text
 1. **Structured Content** - Content is stored as JSON, not just HTML
 2. **Future-Proof** - Easy to export/migrate content
 3. **Better Search** - Structured content works better with Typesense
 4. **Extensible** - Easy to add custom block types (images, etc.)
 5. **Sanitization** - Inherently safer than HTML parsing
 ## Next Steps
 1. Install the npm packages using one of the methods above
 2. Test the editor functionality
 3. Verify image processing works correctly
 4. Optional: Add custom image block types for enhanced image handling
 ## File Structure
 ```
 frontend/src/
 ├── components/stories/
 │   ├── PortableTextEditor.tsx      # New editor component
 │   └── RichTextEditor.tsx          # Original (can be removed after testing)
 ├── lib/portabletext/
 │   ├── schema.ts                   # Portable Text schema and types
 │   └── conversion.ts               # HTML ↔ Portable Text conversion
 └── app/
    ├── add-story/page.tsx          # Updated to use PortableTextEditor
    └── stories/[id]/edit/page.tsx  # Updated to use PortableTextEditor
 ```
 The implementation is backward compatible and maintains all existing functionality while providing the benefits of structured content editing.

 # Refresh Token Implementation
 ## Overview
 This document describes the refresh token functionality implemented for StoryCove, allowing users to stay authenticated for up to 2 weeks with automatic token refresh.
 ## Architecture
 ### Token Types
 1. **Access Token (JWT)**
   - Lifetime: 24 hours
   - Stored in: httpOnly cookie + localStorage
   - Used for: API authentication
   - Format: JWT with subject and libraryId claims
 2. **Refresh Token**
   - Lifetime: 14 days (2 weeks)
   - Stored in: httpOnly cookie + database
   - Used for: Generating new access tokens
   - Format: Secure random 256-bit token (Base64 encoded)
 ### Token Flow
 1. **Login**
   - User provides password
   - Backend validates password
   - Backend generates both access token and refresh token
   - Both tokens sent as httpOnly cookies
   - Access token also returned in response body for localStorage
 2. **API Request**
   - Frontend sends access token via Authorization header and cookie
   - Backend validates access token
   - If valid: Request proceeds
   - If expired: Frontend attempts token refresh
 3. **Token Refresh**
   - Frontend detects 401/403 response
   - Frontend automatically calls `/api/auth/refresh`
   - Backend validates refresh token from cookie
   - If valid: New access token generated and returned
   - If invalid/expired: User redirected to login
 4. **Logout**
   - Frontend calls `/api/auth/logout`
   - Backend revokes refresh token in database
   - Both cookies cleared
   - User redirected to login page
 ## Backend Implementation
 ### New Files
 1. **`RefreshToken.java`** - Entity class
   - Fields: id, token, expiresAt, createdAt, revokedAt, libraryId, userAgent, ipAddress
   - Helper methods: isExpired(), isRevoked(), isValid()
 2. **`RefreshTokenRepository.java`** - Repository interface
   - findByToken(String)
   - deleteExpiredTokens(LocalDateTime)
   - revokeAllByLibraryId(String, LocalDateTime)
   - revokeAll(LocalDateTime)
 3. **`RefreshTokenService.java`** - Service class
   - createRefreshToken(libraryId, userAgent, ipAddress)
   - verifyRefreshToken(token)
   - revokeToken(token)
   - revokeAllByLibraryId(libraryId)
   - cleanupExpiredTokens() - Scheduled daily at 3 AM
 ### Modified Files
 1. **`JwtUtil.java`**
   - Added `refreshExpiration` property (14 days)
   - Added `generateRefreshToken()` method
   - Added `getRefreshExpirationMs()` method
 2. **`AuthController.java`**
   - Updated `/login` endpoint to create and return refresh token
   - Added `/refresh` endpoint to handle token refresh
   - Updated `/logout` endpoint to revoke refresh token
   - Added helper methods: `getRefreshTokenFromCookies()`, `getClientIpAddress()`
 3. **`SecurityConfig.java`**
   - Added `/api/auth/refresh` to public endpoints
 4. **`application.yml`**
   - Added `storycove.jwt.refresh-expiration: 1209600000` (14 days)
 ## Frontend Implementation
 ### Modified Files
 1. **`api.ts`**
   - Added automatic token refresh logic in response interceptor
   - Added request queuing during token refresh
   - Prevents multiple simultaneous refresh attempts
   - Automatically retries failed requests after refresh
 ### Token Refresh Logic
 ```typescript
 // On 401/403 response:
 1. Check if already retrying -> if yes, queue request
 2. Check if refresh/login endpoint -> if yes, logout
 3. Attempt token refresh via /api/auth/refresh
 4. If successful:
   - Update localStorage with new token
   - Retry original request
   - Process queued requests
 5. If failed:
   - Clear token
   - Redirect to login
   - Reject queued requests
 ```
 ## Security Features
 1. **httpOnly Cookies**: Prevents XSS attacks
 2. **Token Revocation**: Refresh tokens can be revoked
 3. **Database Storage**: Refresh tokens stored server-side
 4. **Expiration Tracking**: Tokens have strict expiration dates
 5. **IP & User Agent Tracking**: Stored for security auditing
 6. **Library Isolation**: Tokens scoped to specific library
 ## Database Schema
 ```sql
 CREATE TABLE refresh_tokens (
    id UUID PRIMARY KEY,
    token VARCHAR(255) UNIQUE NOT NULL,
    expires_at TIMESTAMP NOT NULL,
    created_at TIMESTAMP NOT NULL,
    revoked_at TIMESTAMP,
    library_id VARCHAR(255),
    user_agent VARCHAR(255) NOT NULL,
    ip_address VARCHAR(255) NOT NULL
 );
 CREATE INDEX idx_refresh_token ON refresh_tokens(token);
 CREATE INDEX idx_expires_at ON refresh_tokens(expires_at);
 ```
 ## Configuration
 ### Backend (`application.yml`)
 ```yaml
 storycove:
  jwt:
    expiration: 86400000        # 24 hours (access token)
    refresh-expiration: 1209600000  # 14 days (refresh token)
 ```
 ### Environment Variables
 No new environment variables required. Existing `JWT_SECRET` is used.
 ## Testing
 Comprehensive test suite in `RefreshTokenServiceTest.java`:
 - Token creation
 - Token validation
 - Expired token handling
 - Revoked token handling
 - Token revocation
 - Cleanup operations
 Run tests:
 ```bash
 cd backend
 mvn test -Dtest=RefreshTokenServiceTest
 ```
 ## Maintenance
 ### Automated Cleanup
 Expired tokens are automatically cleaned up daily at 3 AM via scheduled task in `RefreshTokenService.cleanupExpiredTokens()`.
 ### Manual Revocation
 ```java
 // Revoke all tokens for a library
 refreshTokenService.revokeAllByLibraryId("library-id");
 // Revoke all tokens (logout all users)
 refreshTokenService.revokeAll();
 ```
 ## User Experience
 1. **Seamless Authentication**: Users stay logged in for 2 weeks
 2. **Automatic Refresh**: Token refresh happens transparently
 3. **No Interruptions**: API calls succeed even when access token expires
 4. **Backend Restart**: Users must re-login (JWT secret rotates on startup)
 5. **Cross-Device Library Switching**: Automatic library switching when using different devices with different libraries
 ## Cross-Device Library Switching
 ### Feature Overview
 The system automatically detects and switches libraries when you use different devices authenticated to different libraries. This ensures you always see the correct library's data.
 ### How It Works
 **Scenario 1: Active Access Token (within 24 hours)**
 1. Request comes in with valid JWT access token
 2. `JwtAuthenticationFilter` extracts `libraryId` from token
 3. Compares with `currentLibraryId` in backend
 4. **If different**: Automatically switches to token's library
 5. **If same**: Early return (no overhead, just string comparison)
 6. Request proceeds with correct library
 **Scenario 2: Token Refresh (after 24 hours)**
 1. Access token expired, refresh token still valid
 2. `/api/auth/refresh` endpoint validates refresh token
 3. Extracts `libraryId` from refresh token
 4. Compares with `currentLibraryId` in backend
 5. **If different**: Automatically switches to token's library
 6. **If same**: Early return (no overhead)
 7. Generates new access token with correct `libraryId`
 **Scenario 3: After Backend Restart**
 1. `currentLibraryId` is null (no active library)
 2. First request with any token automatically switches to that token's library
 3. Subsequent requests use early return optimization
 ### Performance
 **When libraries match** (most common case):
 - Simple string comparison: `libraryId.equals(currentLibraryId)`
 - Immediate return - zero overhead
 - No datasource changes, no reindexing
 **When libraries differ** (switching devices):
 - Synchronized library switch
 - Datasource routing updated instantly
 - Solr reindex runs asynchronously (doesn't block request)
 - Takes 2-3 seconds in background
 ### Edge Cases
 **Multi-device simultaneous use:**
 - If two devices with different libraries are used simultaneously
 - Last request "wins" and switches backend to its library
 - Not recommended but handled gracefully
 - Each device corrects itself on next request
 **Library doesn't exist:**
 - If token contains invalid `libraryId`
 - Library switch fails with error
 - Request is rejected with 500 error
 - User must re-login with valid credentials
 ## Future Enhancements
 Potential improvements:
 1. Persistent JWT secret (survive backend restarts)
 2. Sliding refresh token expiration (extend on use)
 3. Multiple device management (view/revoke sessions)
 4. Configurable token lifetimes via environment variables
 5. Token rotation (new refresh token on each use)
 6. Thread-local library context for true stateless operation
 ## Summary
 The refresh token implementation provides a robust, secure authentication system that balances user convenience (2-week sessions) with security (short-lived access tokens, automatic refresh). The implementation follows industry best practices and provides a solid foundation for future enhancements.

 # Solr Library Separation Migration Guide
 This guide explains how to migrate existing StoryCove deployments to support proper library separation in Solr search.
 ## What Changed
 The Solr service has been enhanced to support multi-tenant library separation by:
 - Adding a `libraryId` field to all Solr documents
 - Filtering all search queries by the current library context
 - Ensuring complete data isolation between libraries
 ## Migration Options
 ### Option 1: Docker Volume Reset (Recommended for Docker)
 **Best for**: Development, staging, and Docker-based deployments where data loss is acceptable.
 ```bash
 # Stop the application
 docker-compose down
 # Remove only the Solr data volume (preserves database and images)
 docker volume rm storycove_solr_data
 # Restart - Solr will recreate cores with new schema
 docker-compose up -d
 # Wait for services to start, then trigger reindex via admin panel
 ```
 **Pros**: Clean, simple, guaranteed to work
 **Cons**: Requires downtime, loses existing search index
 ### Option 2: Schema API Migration (Production Safe)
 **Best for**: Production environments where you need to preserve uptime.
 **Method A: Automatic (Recommended)**
 ```bash
 # Single endpoint that adds field and migrates data
 curl -X POST "http://your-app-host/api/admin/search/solr/migrate-library-schema" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"
 ```
 **Method B: Manual Steps**
 ```bash
 # Step 1: Add libraryId field via app API
 curl -X POST "http://your-app-host/api/admin/search/solr/add-library-field" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"
 # Step 2: Run migration
 curl -X POST "http://your-app-host/api/admin/search/solr/migrate-library-schema" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"
 ```
 **Method C: Direct Solr API (if app API fails)**
 ```bash
 # Add libraryId field to stories core
 curl -X POST "http://your-solr-host:8983/solr/storycove_stories/schema" \
  -H "Content-Type: application/json" \
  -d '{
    "add-field": {
      "name": "libraryId",
      "type": "string",
      "indexed": true,
      "stored": true,
      "required": false
    }
  }'
 # Add libraryId field to authors core
 curl -X POST "http://your-solr-host:8983/solr/storycove_authors/schema" \
  -H "Content-Type: application/json" \
  -d '{
    "add-field": {
      "name": "libraryId",
      "type": "string",
      "indexed": true,
      "stored": true,
      "required": false
    }
  }'
 # Then run the migration
 curl -X POST "http://your-app-host/api/admin/search/solr/migrate-library-schema" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"
 ```
 **Pros**: No downtime, preserves service availability, automatic field addition
 **Cons**: Requires API access
 ### Option 3: Application-Level Migration (Recommended for Production)
 **Best for**: Production environments with proper admin access.
 1. **Deploy the code changes** to your environment
 2. **Access the admin panel** of your application
 3. **Navigate to search settings**
 4. **Use the "Migrate Library Schema" button** or API endpoint:
   ```
   POST /api/admin/search/solr/migrate-library-schema
   ```
 **Pros**: User-friendly, handles all complexity internally
 **Cons**: Requires admin access to application
 ## Step-by-Step Migration Process
 ### For Docker Deployments
 1. **Backup your data** (optional but recommended):
   ```bash
   # Backup database
   docker-compose exec postgres pg_dump -U storycove storycove > backup.sql
   ```
 2. **Pull the latest code** with library separation fixes
 3. **Choose migration approach**:
   - **Quick & Clean**: Use Option 1 (volume reset)
   - **Production**: Use Option 2 or 3
 4. **Verify migration**:
   - Log in with different library passwords
   - Perform searches to confirm isolation
   - Check that new content gets indexed with library IDs
 ### For Kubernetes/Production Deployments
 1. **Update your deployment** with the new container images
 2. **Add the libraryId field** to Solr schema using Option 2
 3. **Use the migration endpoint** (Option 3):
   ```bash
   kubectl exec -it deployment/storycove-backend -- \
     curl -X POST http://localhost:8080/api/admin/search/solr/migrate-library-schema
   ```
 4. **Monitor logs** for successful migration
 ## Verification Steps
 After migration, verify that library separation is working:
 1. **Test with multiple libraries**:
   - Log in with Library A password
   - Add/search content
   - Log in with Library B password
   - Confirm Library A content is not visible
 2. **Check Solr directly** (if accessible):
   ```bash
   # Should show documents with libraryId field
   curl "http://solr:8983/solr/storycove_stories/select?q=*:*&fl=id,title,libraryId&rows=5"
   ```
 3. **Monitor application logs** for any library separation errors
 ## Troubleshooting
 ### "unknown field 'libraryId'" Error
 **Problem**: `ERROR: [doc=xxx] unknown field 'libraryId'`
 **Cause**: The Solr schema doesn't have the libraryId field yet.
 **Solutions**:
 1. **Use the automated migration** (adds field automatically):
   ```bash
   curl -X POST "http://your-app/api/admin/search/solr/migrate-library-schema"
   ```
 2. **Add field manually first**:
   ```bash
   # Add field via app API
   curl -X POST "http://your-app/api/admin/search/solr/add-library-field"
   # Then run migration
   curl -X POST "http://your-app/api/admin/search/solr/migrate-library-schema"
   ```
 3. **Direct Solr API** (if app API fails):
   ```bash
   # Add to both cores
   curl -X POST "http://solr:8983/solr/storycove_stories/schema" \
     -H "Content-Type: application/json" \
     -d '{"add-field":{"name":"libraryId","type":"string","indexed":true,"stored":true}}'
   curl -X POST "http://solr:8983/solr/storycove_authors/schema" \
     -H "Content-Type: application/json" \
     -d '{"add-field":{"name":"libraryId","type":"string","indexed":true,"stored":true}}'
   ```
 4. **For development**: Use Option 1 (volume reset) for clean restart
 ### Migration Endpoint Returns Error
 Common causes:
 - Solr is not available (check connectivity)
 - No active library context (ensure user is authenticated)
 - Insufficient permissions (check JWT token/authentication)
 ### Search Results Still Mixed
 This indicates incomplete migration:
 - Clear all Solr data and reindex completely
 - Verify that all documents have libraryId field
 - Check that search queries include library filters
 ## Environment-Specific Notes
 ### Development
 - Use Option 1 (volume reset) for simplicity
 - Data loss is acceptable in dev environments
 ### Staging
 - Use Option 2 or 3 to test production migration procedures
 - Verify migration process before applying to production
 ### Production
 - **Always backup data first**
 - Use Option 2 (Schema API) or Option 3 (Admin endpoint)
 - Plan for brief performance impact during reindexing
 - Monitor system resources during bulk reindexing
 ## Performance Considerations
 - **Reindexing time**: Depends on data size (typically 1000 docs/second)
 - **Memory usage**: May increase during bulk indexing
 - **Search performance**: Minimal impact from library filtering
 - **Storage**: Slight increase due to libraryId field
 ## Rollback Plan
 If issues occur:
 1. **Immediate**: Restart Solr to previous state (if using Option 1)
 2. **Schema revert**: Remove libraryId field via Schema API
 3. **Code rollback**: Deploy previous version without library separation
 4. **Data restore**: Restore from backup if necessary
 This migration enables proper multi-tenant isolation while maintaining search performance and functionality.

 ```
 ## ✅ Best Practices Implemented
 ### 🔒 **Security**
 - **Environment-Aware SSL Configuration**
  - Production: Full certificate validation with custom truststore support
  - Development: Optional certificate validation for local development
 - **Proper Authentication**: Basic auth with secure credential management
 - **Connection Security**: TLS 1.3 support with hostname verification
 ### 🏗️ **Configuration Management**
 - **Externalized Configuration**: JSON/YAML files instead of hardcoded values
 - **Environment-Specific Settings**: Different configs for dev/staging/prod
 - **Type-Safe Properties**: Strongly-typed configuration classes
 - **Validation**: Configuration validation at startup
 ### 📈 **Scalability & Performance**
 - **Connection Pooling**: Configurable connection pool with timeout management
 - **Environment-Aware Sharding**:
  - Development: 1 shard, 0 replicas (single node)
  - Production: 3 shards, 1 replica (high availability)
 - **Bulk Operations**: Optimized bulk indexing with configurable batch sizes
 - **Index Templates**: Automatic application of settings to new indexes
 ### 🔄 **Index Lifecycle Management**
 - **Automated Index Rollover**: Based on size, document count, and age
 - **Hot-Warm-Cold Architecture**: Optimized storage costs
 - **Retention Policies**: Automatic cleanup of old data
 - **Force Merge**: Optimization in warm phase
 ### 📊 **Monitoring & Observability**
 - **Health Checks**: Automatic cluster health monitoring
 - **Spring Boot Actuator**: Health endpoints for monitoring systems
 - **Metrics Collection**: Configurable performance metrics
 - **Slow Query Detection**: Configurable thresholds for query performance
 ### 🛡️ **Error Handling & Resilience**
 - **Connection Retry Logic**: Automatic retry with backoff
 - **Circuit Breaker Pattern**: Fail-fast for unhealthy clusters
 - **Graceful Degradation**: Graceful handling when OpenSearch unavailable
 - **Detailed Error Logging**: Comprehensive error tracking
 ## 🚀 Usage
 ### Development Environment
 ```yaml
 # application-development.yml
 storycove:
  opensearch:
    profile: development
    security:
      ssl-verification: false
      trust-all-certificates: true
    indices:
      default-shards: 1
      default-replicas: 0
 ```
 ### Production Environment
 ```yaml
 # application-production.yml
 storycove:
  opensearch:
    profile: production
    security:
      ssl-verification: true
      trust-all-certificates: false
      truststore-path: /etc/ssl/opensearch-truststore.jks
    indices:
      default-shards: 3
      default-replicas: 1
 ```
 ## 📋 Environment Variables
 ### Required
 - `OPENSEARCH_PASSWORD`: Admin password for OpenSearch cluster
 ### Optional (with sensible defaults)
 - `OPENSEARCH_HOST`: Cluster hostname (default: localhost)
 - `OPENSEARCH_PORT`: Cluster port (default: 9200)
 - `OPENSEARCH_USERNAME`: Admin username (default: admin)
 - `OPENSEARCH_SSL_VERIFICATION`: Enable SSL verification (default: false for dev)
 - `OPENSEARCH_MAX_CONN_TOTAL`: Max connections (default: 30 for dev, 200 for prod)
 ## 🎯 Index Templates
 Index templates automatically apply configuration to new indexes:
 ```json
 {
  "index_patterns": ["stories_*"],
  "template": {
    "settings": {
      "number_of_shards": "#{ENV_SPECIFIC}",
      "analysis": {
        "analyzer": {
          "story_analyzer": {
            "type": "standard",
            "stopwords": "_english_"
          }
        }
      }
    }
  }
 }
 ```
 ## 🔍 Health Monitoring
 Access health information:
 - **Application Health**: `/actuator/health`
 - **OpenSearch Specific**: `/actuator/health/opensearch`
 - **Detailed Metrics**: Available when `enable-metrics: true`
 ## 🔄 Deployment Strategy
 Recommended deployment approach:
 1. **Development**: Test OpenSearch configuration locally
 2. **Staging**: Validate performance and accuracy in staging environment
 3. **Production**: Deploy with proper monitoring and backup procedures
 ## 🛠️ Troubleshooting
 ### Common Issues
 1. **SSL Certificate Errors**
   - Development: Set `trust-all-certificates: true`
   - Production: Provide valid truststore path
 2. **Connection Timeouts**
   - Increase `connection.timeout` values
   - Check network connectivity and firewall rules
 3. **Index Creation Failures**
   - Verify cluster health with `/actuator/health/opensearch`
   - Check OpenSearch logs for detailed error messages
 4. **Performance Issues**
   - Monitor slow queries with configurable thresholds
   - Adjust bulk operation settings
   - Review shard allocation and replica settings
 ## 🔮 Future Enhancements
 - **Multi-Cluster Support**: Connect to multiple OpenSearch clusters
 - **Advanced Security**: Integration with OpenSearch Security plugin
 - **Custom Analyzers**: Domain-specific text analysis
 - **Index Aliases**: Zero-downtime index updates
 - **Machine Learning**: Integration with OpenSearch ML features
