 # Changelog
 
+## 2025-04-18 - 5.9.2 - fix(documentation)
+Update search API documentation to replace deprecated searchWithLucene examples with the unified search(query) API and clarify its behavior.
+
+- Replaced 'searchWithLucene' examples with 'search(query)' in the README.
+- Updated explanation to detail field-specific exact match, partial word regex search, multi-word literal matching, and handling of empty queries.
+- Clarified guidelines for creating MongoDB text indexes on searchable fields for optimized search performance.
+
+## 2025-04-18 - 5.9.1 - fix(search)
+Refactor search tests to use unified search API and update text index type casting
+
+- Replaced all calls from searchWithLucene with search in test/search tests
+- Updated text index specification in the collection class to use proper type casting
+
+## 2025-04-18 - 5.9.0 - feat(collections/search)
+Improve text index creation and search fallback mechanisms in collections and document search methods
+
+- Auto-create a compound text index on all searchable fields in SmartdataCollection with a one-time flag to prevent duplicate index creation.
+- Refine the search method in SmartDataDbDoc to support exact field matches and safe regex fallback for non-Lucene queries.
+
 ## 2025-04-17 - 5.8.4 - fix(core)
 Update commit metadata with no functional code changes

 The search functionality includes:
 
 - `@searchable()` decorator for marking fields as searchable
-- `getSearchableFields()` to retrieve all searchable fields for a class
-- `search()` method for basic search (requires MongoDB text index)
-- `searchWithLucene()` method with robust fallback mechanisms
-- Support for field-specific searches, wildcards, and boolean operators
-- Automatic fallback to regex-based search if MongoDB text search fails
+- `getSearchableFields()` to list searchable fields for a model
+- `search(query: string)` method supporting:
+  - Field-specific exact matches (`field:value`)
+  - Case-insensitive partial matches across all searchable fields
+  - Multi-word literal matching
+  - Empty queries returning all documents
+- Automatic escaping of special characters to prevent regex injection

 ### Search Optimization
 
-- Create MongoDB text indexes for collections that need advanced search operations
-- Use `searchWithLucene()` for robust searches with fallback mechanisms
-- Prefer field-specific searches when possible for better performance
-- Use simple term queries instead of boolean operators if you don't have text indexes
+- (Optional) Create MongoDB text indexes on searchable fields to speed up full-text search
+- Use `search(query)` for all search operations (field:value, partial matches, multi-word)
+- Prefer field-specific exact matches when possible for optimal performance
+- Avoid unnecessary complexity in query strings to keep regex searches efficient
