What exactly is it that this parameter does?
It just tells the store to leverage the org.apache.slide.store.impl.rdbms.expression stuff and the database.
Without it it simply loads and examines each and every resource within the search scope.
Because it does work exceptionally well, doing the same search as before on 40000 files (which gave an OutOfMemoryException after 15 minutes) took about 1.4 seconds now. Now, given the performance boast shouldn't this parameter be on by default when using a JDBC store?
I'm not sure how well it's tested with other DB stores (besides MySQL).
