1. TEXT SEARCH (PostgreSQL ILIKE):
   - Fast: ~0.7ms average
   - Exact substring matching
   - Case-insensitive
   - Good for keyword searches

2. VECTOR SEARCH - PostgreSQL pgvector (HNSW):
   - Speed: ~{:.1f}ms average
   - Built into PostgreSQL
   - No additional infrastructure needed
   - Good for single-database architecture

3. VECTOR SEARCH - Qdrant (HNSW):
   - Speed: ~{:.1f}ms average
   - Dedicated vector database
   - Better for large-scale deployments
   - Supports more advanced vector operations

4. OBJECT SEARCH (PostgreSQL JSON):
   - Very fast: ~{:.1f}ms average
   - Uses JSON containment operator
   - Works with YOLO metadata
   - Best for visual object queries

RECOMMENDATION:
- For simple keyword searches: PostgreSQL ILIKE
- For semantic search with single DB: PostgreSQL pgvector
- For scalability: Qdrant
- For visual content: PostgreSQL JSON with YOLO metadata
