YOSEMETI-SEARCH DOSEN'T WORK PROPERLY

Example: COMMAND F- Type a key word in a folder that I know the word is in a file name and it doesn't "find" it. Tried the little drop down criteria menus of "Filename matches: ; Name: Filename or Everything.

Criteria should always be available which it is not or I can't find it.

Very annoying. The previous operating systems search engines worked fine.
