## 2025-04-06 - 5.5.0 - feat(search)
|
||||||
|
Enhance search functionality with robust Lucene query transformation and reliable fallback mechanisms
|
||||||
|
|
||||||
|
- Improve Lucene adapter to properly structure $or queries for term, phrase, wildcard, and fuzzy search
|
||||||
|
- Implement and document a robust searchWithLucene method with fallback to in-memory filtering
|
||||||
|
- Update readme and tests with extensive examples for @searchable fields and Lucene-based queries
|
||||||
|
|
||||||
|
## 2025-04-06 - 5.4.0 - feat(core)
|
||||||
|
Refactor file structure and update dependency versions
|
||||||
|
|
||||||
|
- Renamed files and modules from 'smartdata.classes.*' to 'classes.*' and adjusted corresponding import paths.
|
||||||
|
- Updated dependency versions: '@push.rocks/smartmongo' to ^2.0.11, '@tsclass/tsclass' to ^8.2.0, and 'mongodb' to ^6.15.0.
|
||||||
|
- Renamed dev dependency packages from '@gitzone/...' to '@git.zone/...' and updated '@push.rocks/tapbundle' and '@types/node'.
|
||||||
|
- Fixed YAML workflow command: replaced 'pnpm install -g @gitzone/tsdoc' with 'pnpm install -g @git.zone/tsdoc'.
|
||||||
|
- Added package manager configuration and pnpm-workspace.yaml for built dependencies.
|
||||||
|

|

|
|
||||||
|
```typescript
|
||||||
|
// Define a model with searchable fields
|
||||||
|

|

class Product extends SmartDataDbDoc<Product, Product> {

|
}
|
||||||
|
|
||||||
|
// Get all fields marked as searchable for a class
|
||||||
|
const searchableFields = getSearchableFields('Product'); // ['name', 'description', 'category']
|
||||||
|
|
||||||
|
// Basic search across all searchable fields
|
||||||
|
const iPhoneProducts = await Product.searchWithLucene('iPhone');

|
const macProducts = await Product.searchWithLucene('Mac*');
|

|
|

|
// Search in specific fields with partial words
|
||||||
|
const laptopResults = await Product.searchWithLucene('description:laptop');
|
||||||
|
|
||||||
|
// Search is case-insensitive
|
||||||
|
const results1 = await Product.searchWithLucene('electronics');
|
||||||
|
const results2 = await Product.searchWithLucene('Electronics');
|
||||||
|
// results1 and results2 will contain the same documents
|
||||||
|
|
||||||
|
// Using boolean operators (requires text index in MongoDB)
|
||||||
|
const wirelessOrLaptop = await Product.searchWithLucene('wireless OR laptop');
|
||||||
|
|
||||||
|
// Negative searches
|
||||||
|
const electronicsNotSamsung = await Product.searchWithLucene('Electronics NOT Samsung');
|
||||||
|
|
||||||
|
// Phrase searches
|
||||||
|
const exactPhrase = await Product.searchWithLucene('"high-speed blender"');
|
||||||
|
|
||||||
|
// Grouping with parentheses
|
||||||
|
const complexQuery = await Product.searchWithLucene('(wireless OR bluetooth) AND Electronics');
|
||||||
|
```
|
||||||
|
|
||||||
|
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
