API Data source results clear

I have a search input field that retrieves results from an API and displays it in a list view.

Is it possible to clear the results without sending an empty search string to the API again?

I want the user to clear the results by clicking the X in the search type input field. Currently I can only show and hide results by using the length function:

dmx-show=“search.value.length()”

But as soon as I start typing in the field my previous results obviously displays again.
