Search criteria to omit results

Hi - I would like to search like this: 2020 .pptx !MIKE where all .pptx files that contain 2020 and do NOT contain MIKE in the name are displayed.

Have you tried doing what it says here?

I don’t see a specific way to achieve this. Yes I did find that page. I may want “any file type except pdf”.

Other alternatives might be: Mike Finance -2020 which would eliminate files that match Mike and Finance but not with the number 2020.
