+## Search Capability (SearXNG + Crawl4AI)
+
+Timmy has a self-hosted search backend requiring **no paid API key**.
+
+### Tools
+
+| Tool | Module | Description |
+|------|--------|-------------|
+| `web_search(query)` | `timmy/tools/search.py` | Meta-search via SearXNG — returns ranked results |
+| `scrape_url(url)` | `timmy/tools/search.py` | Full-page scrape via Crawl4AI → clean markdown |
+
+Both tools are registered in the **orchestrator** (full) and **echo** (research) toolkits.
+
+### Configuration
+
+| Env Var | Default | Description |
+|---------|---------|-------------|
+| `TIMMY_SEARCH_BACKEND` | `searxng` | `searxng` or `none` (disable) |
+| `TIMMY_SEARCH_URL` | `http://localhost:8888` | SearXNG base URL |
+| `TIMMY_CRAWL_URL` | `http://localhost:11235` | Crawl4AI base URL |
+
+Inside Docker Compose (when `--profile search` is active), the dashboard
+uses `http://searxng:8080` and `http://crawl4ai:11235` by default.
+
+### Starting the services
+
+```bash
+# Start SearXNG + Crawl4AI alongside the dashboard:
+docker compose --profile search up
+
+# Or start only the search services:
+docker compose --profile search up searxng crawl4ai
+```
+
+### Graceful degradation
+
+- If `TIMMY_SEARCH_BACKEND=none`: tools return a "disabled" message.
+- If SearXNG or Crawl4AI is unreachable: tools log a WARNING and return an
+  error string — the app never crashes.
