Right now Clan Search only searches names, which is useful, but doesn't always get the right result! For example just today I searched for "inverted" in clans, and concluded there was nothing relevant, despite the I.R.I.S ("Inverted [Rosette] Institute and Study") clan being a thing. It would be easier to find what you want if the descriptions were searchable as well, since they usually contain relevant information, and not everything can or does fit in the name.
