Function usePdfSearch

usePdfSearch(): PdfSearch
Full-text search over the document, with highlights painted by the viewer.

There is one searcher per viewer — the provider owns it — so several components can call this hook and stay in sync. It is reset automatically when a different document is opened.

Returns PdfSearch
The current pdf search state and actions.
Example
```
const { query, setQuery, currentIndex, matchCount, goToNext } = usePdfSearch();
return (
  <>
    <input value={query} onChange={(e) => setQuery(e.target.value)} />
    <span>{(currentIndex ?? -1) + 1} / {matchCount}</span>
    <button onClick={() => void goToNext()}>Next</button>
  </>
);
```
