# Search Media Items (Unified)
Search and filter media items with fuzzy matching support.
**Note:** All text filters use fuzzy matching via PostgreSQL pg_trgm (threshold: 0.3 similarity). This handles typos and partial matches automatically. Use quotes for exact match.
**Endpoint**: `GET /api/media-items/search`
**Auth**: Required

| library_id | string | Yes | Filter to specific library (UUID) |
| limit | integer | No | Number of results (default 50, max 200) |
| offset | integer | No | Number to skip for pagination |
### Filter Parameters (All Fuzzy Except Years/Booleans)

## Search Behavior
### Fuzzy Search (Default)
Handles typos and partial matches automatically:
- `"asimov"` → matches "Asimov, Isaac", "Asimov, Foundation"
- `"scifi"` → matches "Sci-Fi", "Science Fiction"
- `"azimov"` → matches "Asimov, Isaac" (typo tolerance)
### Exact Search (With Quotes)
Use double quotes for exact phrase matching:
- `"\"Foundation and Empire\""` → only "Foundation and Empire"
- `"\"Asimov, Isaac\""` → only "Asimov, Isaac"
### Filter Behavior
**Text filters (fuzzy):**
- `author_filter=asimov` → fuzzy matches author field
- `tags_filter=scifi` → fuzzy matches tags field
**Exact filters:**
- `year_min=2000&year_max=2010` → exact year range
- `has_cover=true` → exact boolean match
