It just pulls up way too much information. If you simply search for the name of a game, it pulls up pages and pages of results with that games name. It could be mods, language options, or just posts mentioning the name of the game. I may just not be filtering as much as I should and that is probably my bad, but I usually have to check through several pages of results just to find a single game. And I wouldn't even know how to begin searching for a specific post within a thread. Granted these are probably a reflection on my inability to filter properly and not a reflection on the search function as a whole, but it is still not a great option for me.
