By default we would have the same simple algorithm as we have now, but we could/should turn it into smarter/faster one. e.g. merge qualifiers only once, match on set intersection not being empty In this case we would have to check if MDR can be changed in such a way that our data wouldn't be stale / invalid. e.g. something would pull the X level MDR "rug" under our feet / "database" View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4267634#...
