The built-in search is a plain case-insensitive substring match. When you need fuzzy, accent-insensitive, ranked, or remote results, hand the whole search off to searchCallback — the component stays dependency-free and just renders what you return.

searchCallback is called as (term, signal) => Promise<T[]>. Wire the AbortSignal into fetch so that when the user keeps typing, the previous in-flight request is aborted and its stale results never overwrite the newer ones.
