Search Mode Selection
| Mode | Speed | Quality | Best For |
|---|---|---|---|
| search | Fast | Good | Exact keywords, known terms |
| vsearch | Medium | Better | Conceptual queries, synonyms |
| query | Slow | Best | Complex questions, uncertain terms |
Performance note: vsearch and query have ~1 minute cold start latency for vector initialization. Prefer search for interactive use.
