Not showing "No search results found"?

Question

MODX

Good afternoon.
On the site of the online store, a search with filters is organized. And if the value is present on the site, then everything is ok with the search. But if the task is not a correct request, then it displays an empty page. Although it should display the inscription "no results found"
Help me find out what the problem is.
Template Code

<div class="wrapper_inner front">
            
          
        </div>
