The constraints in the query are separated based on the vertically partitioned, inverted indexes. A document identifier iterator is obtained for each of the constraints, wherein each document identifier iterator is associated with a posting list, and wherein each posting list is ordered by document identifier order. A run-time join of the posting lists is performed to obtain a final result set.
