Improvement Plan - Fuse.js Optimization Focus

1. Fully Leverage Fuse.js Capabilities

1.1 Enhance Configurability

• <input disabled="" type="checkbox"> Create a comprehensive FuzzyOptions interface exposing Fuse.js options
  • Implementation approach:
    • Expose all relevant Fuse.js options (threshold, distance, location, etc.)
    • Group options logically (matching control, performance control, output control)
    • Add proper TypeScript types and documentation for each option
    • Create sensible defaults for different use cases (loose matching, exact matching, etc.)
    • Add option validation with clear error messages
    • Implement runtime option updates via setOptions() method

1.2 Improve Weighted Field Support

• <input disabled="" type="checkbox"> Enhance ObjectSorter to support field weights like ArticleSearch
  • Implementation approach:
    • Add ability to specify weight per field in ObjectSorter
    • Maintain backward compatibility with current simple array of fields
    • Create examples of different weighting strategies
    • Add tests demonstrating the effect of different field weights
    • Include weight settings in all relevant documentation

1.3 Add Extended Search Capabilities

• <input disabled="" type="checkbox"> Implement Fuse.js extended search syntax support
  • Implementation approach:
    • Add support for Fuse.js extended search syntax (AND, OR, exact matching)
    • Create helper methods to build complex search queries
    • Add examples of extended search usage in documentation
    • Create tests for complex search patterns
    • Implement query validation for extended search syntax

2. Performance Optimization

2.1 Optimize Index Creation

• <input disabled="" type="checkbox"> Implement proper Fuse.js index management
  • Implementation approach:
    • Create persistent indices instead of rebuilding for each search
    • Add incremental index updates when items are added/removed
    • Implement proper index serialization and deserialization
    • Add option to lazily rebuild indices
    • Create tests measuring index creation performance

2.2 Implement Basic Caching

• <input disabled="" type="checkbox"> Add results caching for repeated queries
  • Implementation approach:
    • Implement simple Map-based cache for query results
    • Add cache invalidation on dictionary/object changes
    • Create configurable cache size limits
    • Add cache hit/miss tracking for debugging
    • Implement optional cache persistence

2.3 Add Async Processing for Large Datasets

• <input disabled="" type="checkbox"> Implement non-blocking search operations for large datasets
  • Implementation approach:
    • Create async versions of search methods that don't block main thread
    • Implement chunked processing for large dictionaries
    • Add progress tracking for long operations
    • Create cancellable search operations
    • Add proper promise handling and error propagation
    • Measure performance difference between sync and async methods

3. API Improvements

3.1 Standardize Method Naming

• <input checked="" disabled="" type="checkbox"> Standardize all method names for consistency
  • Implementation completed:
    • Renamed getClosestMatchForString to findClosestMatch
    • Renamed getChangeScoreForString to calculateScores
    • Created backward compatibility aliases with @deprecated tags
    • Updated all tests with new method names
    • ✓ Tests pass and build succeeds

3.2 Add Chainable API

• <input disabled="" type="checkbox"> Create a more fluent API for complex searches
  • Implementation approach:
    • Implement chainable methods for setting options
    • Add result transformation methods (map, filter, sort)
    • Create fluent search building interface
    • Implement method chaining for filters and transformations
    • Add proper TypeScript type inference for chainable methods
    • Create examples demonstrating the chainable API

3.3 Enhance Return Types

• <input disabled="" type="checkbox"> Improve result objects with more useful information
  • Implementation approach:
    • Standardize return types across all search methods
    • Add richer match information (character positions, context)
    • Implement highlighting helpers for match visualization
    • Add metadata to search results (time taken, options used)
    • Create proper TypeScript interfaces for all result types

4. Documentation and Examples

4.1 Create Comprehensive Documentation

• <input disabled="" type="checkbox"> Improve documentation with Fuse.js-specific information
  • Implementation approach:
    • Generate TypeDoc documentation from JSDoc comments
    • Create specific sections for Fuse.js integration details
    • Add visual diagrams showing how Fuse.js is utilized
    • Document all configuration options with examples
    • Add performance guidelines based on Fuse.js recommendations

4.2 Create Usage Examples

• <input disabled="" type="checkbox"> Add specialized examples for common search patterns
  • Implementation approach:
    • Create examples for typical search scenarios (autocomplete, filtering, etc.)
    • Add examples of weighted searching for different use cases
    • Demonstrate extended search syntax with examples
    • Create comparative examples showing different configuration effects
    • Add performance optimization examples

5. Testing Enhancements

5.1 Add Fuse.js-specific Tests

    • Add tests for all Fuse.js configuration options
    • Create performance comparison tests for different settings
    • Implement tests for extended search syntax
    • Add tests for very large datasets
    • Create index persistence and rebuilding tests

5.2 Add Edge Case Tests

• <input disabled="" type="checkbox"> Improve test coverage for Fuse.js edge cases

    • Add tests for multilingual content
    • Create tests for zero-match and all-match cases
    • Implement tests for threshold boundary conditions
    • Add tests for unusual scoring scenarios
