How to set priorities in search based on file type in fedora kde

for instance when I am trying to search for an appimage of signal I get this list of files I will never open like .asc .dds whereas .appimage I am trying to search is so far behind (32nd entry) that you would need to scroll really far to get to it

Try searching for Appimage instead of signal.
That should show all the installed appimages which is probably a much shorter list than the files that contain signal in the name.
