+### ✅ Pagination +- Efficient offset-based pagination +- Configurable page size (1-100) +- Total count and pages metadata +- Handles out-of-range pages gracefully + +### ✅ Search +- Full-text search across question text +- Search in explanations +- Search in tags +- Case-insensitive matching +- Handles special characters + +### ✅ Filtering +- Filter by category (UUID) +- Filter by difficulty (easy/medium/hard) +- Combine multiple filters +- Invalid UUIDs handled gracefully + +### ✅ Sorting +- Sort by multiple fields +- Ascending or descending order +- Invalid sort fields default to createdAt +- Consistent ordering + +### ✅ Response Data +- Calculated accuracy percentage +- Complete question details including correctAnswer (admin only) +- Category information +- Active/inactive status +- Timestamps + +## Performance Considerations + +1. **Limit:** Maximum 100 questions per page to prevent performance issues +2. **Indexing:** Database indexes on frequently queried fields (categoryId, difficulty, isActive) +3. **Pagination:** Offset-based pagination is efficient for moderate dataset sizes +4. **Search:** Uses SQL LIKE for search - consider full-text indexes for large datasets + +## Testing + +Run the comprehensive test suite: + +```bash +node test-admin-questions-pagination.js +``` + +The test suite covers: +- ✅ Authorization (35 tests) +- ✅ Pagination (8 tests)
