Advanced Search & Filter

Overview

Implement advanced search and filtering capabilities:

• Priority-based filtering (low, medium, high, urgent)
• Tag-based search and categorization
• Date range filtering (due dates, creation dates)
• Text search with fuzzy matching
• Multi-parameter filtering combinations
• Sort by priority, due date, creation date, alphabetical
• Real-time filtering performance optimization

Pre-execution

Before implementing filters, verify: "Confirm search requirements and performance expectations?"

Post-execution

Test search functionality with various filter combinations and measure performance

Implementation Guidelines

1. Priority Filtering

• Implement filtering by priority levels (low, medium, high, urgent)
• Add multi-select capability for priority ranges
• Create UI controls for priority-based filtering
• Optimize database queries for priority filtering

2. Tag-Based Search

• Enable search by tags/categories
• Implement tag autocomplete suggestions
• Support multiple tag selection and exclusion
• Create tag management interface in UI

3. Date Range Filtering

• Add date range selection for due dates
• Implement creation/modification date filtering
• Create calendar-based date pickers
• Support relative date filters (today, this week, etc.)

4. Text Search Capabilities

• Implement fuzzy text matching for task titles/descriptions
• Add search highlighting for matched terms
• Support boolean operators (AND, OR, NOT)
• Implement search result ranking

5. Multi-Parameter Filtering

• Combine multiple filter parameters in single queries
• Implement filter chaining and exclusion logic
• Optimize complex query performance
• Cache frequently used filter combinations

6. Sorting Functionality

• Sort by priority (high to low, low to high)
• Sort by due date (ascending, descending)
• Sort by creation date (newest, oldest)
• Sort alphabetically by title

7. Performance Optimization

• Implement pagination for large result sets
• Use database indexes for common filter combinations
• Optimize query execution time for complex filters
• Add loading indicators for search operations
