public class ForkJoinQueryHandler
extends DBQueryHandler

Handles the actual database query. The handle must return a list of rows id's that MAY match. We'll do a filter on all the rows returned so as long as the row list contain all possible matches we'll be OK. Obviously the fewer/closer the match the better the performance will be.
