Stop when you have proof
Show why this lesson detail matters: "Start with this check: The answer cites relevant files rather than only the open file."
Step 1 of 2
The job: you can decide when to trust semantic search and when exact search is safer. Start with this check: The answer cites relevant files rather than only the open file. Keep it small enough to check the result yourself instead of taking the summary on trust.
Index ready — Exact Search, then @Codebase cites the file

- Open Cursor Settings, Indexing and Docs. Instant Grep is on — Cursor indexes this repo locally. There is no separate Resync percentage here; the toggle is the control.
- Exact Search for filterRecentSearches. Three hits in two files — the index is ready enough to grep.
- Attach Codebase, then ask where the helper lives. Semantic context rides with the question.
- The answer cites recentSearches.ts. Same model — the indexed codebase made the citation specific.
Practice next: Now try it: check Indexing & Docs, Exact-Search a symbol, attach @Codebase, and confirm the citation.
