You're more than welcome to message me if just the comm name isn't enough :) There's hpstoryfinders, that I know of. The tags aren't awesome, but there's an eclectic bunch of searches on it. Most fandoms have search comms similar to this, if you search through fandom community tags with LJ, they're usually around the first or second page since there's someone posting or looking for a fic everyday or so. :) Hope I've helped!
The HP fandom tends to have fanfic search communities by pairing. Specifically, you might try snarryficfind and drarryficfind. I haven't come across a LM/HP one though... Hope this helps!
First off, I would need to know which pairings you were looking for. Then I'd be able to offer any number of comms and sites.
ETA: Never mind, I checked your comments and saw which pairings you wanted.
Drarry Fic Find (http://drarryficfind.livejournal.com/) for Harry/Draco
Snarry Fic Find (http://snarryficfind.livejournal.com/) for Harry/Snape
And for just about any pairing, there's painless_j's Ginormous HP Rec List (http://painless-j.net/blog/category/hp-recs-masterlist/) that nearly everyone in the HP fandom has gone to at one time or another. It's divided into pairings and has summaries for each story linked.
Likewise, there are several archives that cater to certain pairings, like The Hex Files for Harry/Draco, Walking The Plank for Harry/Snape. Then there's The Quidditch Pitch which has multi-pairings, Skyehawke that has tons, Potter Slash Archive that hosts the best of the best HP fic written. Happy hunting!
