## API

```rust
use sift_core::{SearchQuery, SearchOptions, CandidateFilter};

let search = SearchQuery::new(&patterns, SearchOptions::default())?;
search.run(SearchExecution { candidates: &candidates, output, separators, collect: SearchCollection::none() })?;
```

`SearchQuery` compiles the regex once; repeated calls reuse the compiled matcher and searcher cache.
