I am using the Elementor post widget and Ajax pro.
1. Search works as expected
2. When I clear the text, either by manually deleting it, or clicking the X button – the results remain the same, and doesn’t reset (reset = show all)
The X button does not reset the results, it only clears the search phrase, or closes the results box where applicable.
You can set the minimum number of characters to trigger the search to 0, then deleting the phrase will do an “empty” search.
