Club search facility is nonexistent, clan search facility is extremely limited. How about a browser facility like the profile browser which is available for players? A Clan Browser or Club Browser could show a small amount of information about the clan or club in the same way, i.e. a clan profile or club profile.
Clubs are the orphan child of RHP, like the "accident" born to parents who thought they'd completed their family, but it's time they were given equal attention with clans and recognised as useful members of the site in their own right.
