## Issues in `backend/ks_search_tool.py` - **Inconsistent result schema**: `general_search` returns `id/title_guess/content`, `general_search_async` returns `_id/title/description` — causes silent missing fields downstream - **Silent empty return**: `global_fuzzy_keyword_search` returns `[]` with no warning when `datasources_config.json` is missing - **Only top fuzzy match used**: `search_across_all_fields` drops all matches except `matches[0]` - **Dead stub classes**: `BaseModel` and `Field` at the top are unused leftovers from removing Pydantic - **Deprecated API**: `asyncio.get_event_loop()` inside async context — use `asyncio.get_running_loop()` - **`print()` instead of `logging`**: 10+ print calls, can't be silenced in production
