They changed it where quoted terms have the same effect. Hope that helps.I'll second the vote for Everything.
Also if you use Windows key + F you get a global search which has more filters and can search in more places, and also displays the result in a much better format. I have no idea how else to get to it, so it's certainly possible that few people know about it (hey, I didn't until a few minutes ago).
I hated it when Google removed support for '+'. There's now no way to tell the search engine "I really want this word in the result".
