## Suggestions (Lower Confidence)

- **Missing `#[must_use]` on `QueryEngine::new`** - `query.rs:40` (Confidence: 70%) -- The `SearchQuery::new` constructor in `types.rs:303` uses `#[must_use]`; `QueryEngine::new` is a pure constructor returning `Self` that should arguably follow the same convention. However, this is a consistency preference rather than a bug, and the codebase does not annotate all constructors.

- **Doc-example uses `.unwrap()` in non-test code** - `query.rs:30` (Confidence: 65%) -- The `/// # Example` block calls `.unwrap()` on the search result. While the `no_run` attribute prevents execution, using `?` with a `Result`-returning function signature would better model production usage per the project's "no .unwrap() in library code" principle. Since this is a doc comment (not runtime code) and `no_run` is set, impact is minimal.
