	I think the closest you could reasonably get is to have that query  
only return identifiers and pull the heavier stuff from memcached.

	Doing that will reduce your joins and the general IO requirements of  
the DB (assuming the objects are populated, of course).

	There's no search language on top of memcached, though.  It's just  
key/value pairs.
