> If you use Scout's `database` driver with `#[SearchUsingFullText]` columns on Postgres, `Model::search()` ranks results with `ts_rank(...)`. Postgres has to compute the rank for every matching row before it can sort and limit, so a common word on a table with millions of rows can turn a fast GIN index lookup into a timeout.

> If you don't need relevance order, skip Scout for that query and call the query builder directly:
>
> ```php
> Post::query()
>     ->whereFullText(['title', 'body'], $term)
>     ->latest()
>     ->limit(50)
>     ->get();
> ```

> `whereFullText` still uses the GIN index, and ordering by an indexed column lets Postgres stop early. Run `EXPLAIN ANALYZE` on both versions with a common search term to see the difference.
