On GGTracker there are a bunch of filter buttons. 1v1, 2v2, 3v3, and 4v4 are obvious. I think "AM" means the Americas server, "EU" means the European server. But I'm not sure what the other ones are.

I made GGTracker. FFA stands for "Free For All" (who knew you could play a Starcraft free-for-all game?!).
And yes, AM is Americas, SEA is Southeast Asia.
