+  ## Search Media Items
+    
+    Performs a search across all visible media items using partial matching with fuzzy fallback.
+    
+    **Method:** GET
+    
+    **Endpoint:** /api/media-items/search
+    
+    **Authentication:** Required (Bearer token)
+    
+    **Query Parameters:**
+    - `q` (string, required): Search query (minimum 2 characters)
+    
+    **Search Behavior:**
+    1. First performs case-insensitive partial matching across:
+       - Title
+       - Author
+       - Series
+       - Tags
+       - Contributors
+    2. If no results found, falls back to fuzzy search using word_similarity with 0.3 threshold
+    
+    **Response:** Array of media item objects (same structure as List Media Items)
+    
+    **Status Codes:**
+    - 200: Success (results found)
+    - 404: No results found
+    - 400: Missing or invalid query parameter
+    - 401: Unauthorized
+    - 500: Internal server error
+    
+    **Examples:**
+    - Search by title: `q=harry potter`
+    - Search by author: `q=king`
+    - Fuzzy search: `q=hary poter` (will find "harry potter")
+    
+    **Ranking:**
+    Results are ranked by relevance:
+    - Title matches: Highest priority
+    - Author matches: High priority
+    - Series matches: Medium priority
+    - Tag matches: Lower priority
+    - Fuzzy matches: Sorted by similarity score
