# FTS5 Search — Full-Text Search for Session Logs

Index and search all your OpenClaw session logs using SQLite FTS5. Find any conversation, topic, or keyword in milliseconds.

## Quick Start

```python
from search import SearchEngine

engine = SearchEngine(db_path="search.db")

# Index all sessions
engine.index_all(sessions_dir="/path/to/sessions")

# Search
results = engine.search("supervision layer")
# → [<SessionMatch score=0.92 session="2026-05-22-security">]

# Search by topic
results = engine.search("security audit", scope="topic")

# Time range
results = engine.search("deploy", after="2026-05-01", before="2026-05-22")
```
