+### Search Modes
+
+Control which search backend `search_tools()` uses via the `search` parameter:
+
+```python
+# "auto" (default) — tries semantic search first, falls back to local
+tools = toolset.search_tools("manage employees", search="auto")
+
+# "semantic" — semantic API only, raises if unavailable
+tools = toolset.search_tools("manage employees", search="semantic")
+
+# "local" — local BM25+TF-IDF only, no semantic API call
+tools = toolset.search_tools("manage employees", search="local")
+```
+
 Results are automatically scoped to connectors in your linked accounts. See [Semantic Search Example](examples/semantic_search_example.py) for utility tools integration, OpenAI, and LangChain patterns.
