How on earth did you discover that?
It's Boolean logic. I'm a Computer Whiz (though I am not up to the same caliber as Carl), and things like that just jump out at me from books.
You're welcome! I.e., if you want to browse all the Beatles albums except "Let It Be", you type "Beatles -let it be" in the search box of Windows Media Player, so it's (sort of) the same here, too.
I think that by doing that, you'll be searching for "Beatles", "It", and "be". The best bet would be to search for 'Beatles -"let it be"'.
Also, a very helpful piece:
Enclosing a search term in double quotation marks ("") will search for exactly that phrase.
For instance, if Metro said "The painting bug may seem like it ruins you Dynasty, but in actual fact, you can fix it and still be eligible for HoF because you're using legit cheats...", then I could search for "ruins your Dynasty, but in actual", and it would return those exact words.
