Make sure you use filterDelay or 'useDebounce` so it only starts filtering after they have finished typing.

filterDelay : https://primereact.org/datatable/#api.DataTable.props.filterDelay

useDebounce https://primereact.org/hooks/usedebounce/

will it be useable in virtualscroller. because global search better in pagination but not in virtualscroller. You can try in https://primereact.org/datatable/#virtualscroll

[vasubansal333]

That link you pasted doesn't work it just is a default link. Can you please provide a working StackBlitz?

@melloware the first stack almost works. You have to move the useState call inside the app.tsx into the component.
However the generation is not memoized so filter dont work because the 10,000 entries are re-generated on every render

Exactly. But my time is limited so the burden of working reproducer is on the OP not me spending time trying to figure out what is wrong with their reproducer. Only so many hours in the day....
