Any way to just show the files that do not meet the criteria

Hi,
I have a folder that has 489 files and when I search it using two naming conventions I find that I have a mismatch of 2.
Is there a way to show only the files that do not match what I have put into search?
I am running 12.4.3 (Beta) x64
Thank you.
Yours faithfully,
David Findlay

You can negate any search. Exact details depend on the search you're doing.

If you use Tools > Find Files > Advanced, you can also flip search criteria from Match to No-Match to negate them without changing the actual wildcards etc. involved.

Thank you very much. Found the mistakes I was looking for.
