Problem with empty searches

Is there a way to override all actions on submit when the search returns no results? I don’t know if it is a problem with my client’s theme, but in such cases the WooCommerce search page becomes completely blank and the search form disappears. That is, if the user performs a null search, the message appears informing that there are no results, but if the user presses Enter or clicks on the search icon, what I said before happens, the page is empty without any notice or link to go back. I would like that in these cases no action is generated when pressing enter or clicking the magnifying glass.
