All Search Results are returned if no Search Results found for search term

Hi,

If I search for a word that I know is not on the website currently WordPress search returns all results. This can be a little confusing to users as they may think the word has been found.

Is there a way to return no results if no matches are found and all results if no search query is given?

This also seems to happen if I use WP Gridbuilder Search Text Facet.

Thanks
