Preferably an application that you can sync and save. Not sure what alternatives are safe in terms of privacy and security.

I’m not sure what EXACTLY you’d be looking for from a search feature as I’m mostly a light user myself, but there’s a search option which will search the contents of all your notes. I can’t tell you how robust it is, but it does have exclusion (desiredTerm -excludeTerm) search at least, and there’s standard Find/Replace functionality once you’re in the specific note.
