 This issue is obvious when a large polygon is used to within a filter and
 and'ed with a second polygon. Even if one of the spatial condition returns
 a small number of condidate list, the second condition is still go to the
 RTree to get its condidate list. In this case since it's a logical and,
 the first condidate list should be enough to evaluate the filter against
 the second spatial condition.
