Master server
The filter it provided like \gametype or \gamedata is not the sv_steamgroup cvar in server. I know that usign a2s_rules can get the cvar which contain the sv_steamgroup but it is too expensive for the net.

I hope master query has the way to filterate steamgroup like filterate the appid of the game

sv_showtags gives this infomation, should i use \gametype\[grp:steamgourp id] to match my steam gourp?

PHP Code:

sv_showtags
