Narrowing down search

I have the search field set to Anywhere, so I don’t have to think about where the match should be. If there are too many results, I first surround my terms with quotes. If that doesn’t help, I switch the field to Filename.

Unfortunately results then jump to zero, because of the quotes. Now the manual explains the difference between indexed and exact searches, but who remembers that?

Do you know a better search workflow, that avoids adding and deleting quotes?

It’d help if Anywhere supported filename:, like it does tag:, and like the Finder.

Agreed; that’s a feature I’d like to add.
