Why Does FINDER Search NOT Search!!!?

You might try rebuilding the Spotlight index: Rebuild the Spotlight index on your Mac - Apple Support

The Finder never really excelled at finding things. I use EasyFind, which used to be on the App Store and it was free. Since free apps seldom generate sufficient cash flow to motivate continued support and development, it's no longer available. Aww.

Edit: I believe it's still available on the developer's website: https://www.devontechnologies.com/apps/freeware

Find Any File (FAF) is cheap at eight bucks and works just as well: Find Any File (FAF)

I understand. Finder search uses the Spotlight database.
