Do you have any examples?

Is it a third party application feature request?
No
Describe your feature request
If you search for something which has no results, you see the "No results found" template, with the buttons to create a new object and reset filters. Clicking on "Reset filters" does not reset the search input, although you might expect it, since a search is also some sort of filtering, even though it's not part of the filters block.
Therefore I suggest, that "Reset filters" also clears the search input.
