Detailed Description

Class providing an operator which sorts postlists to select max or terms.

This returns true if a has a (strictly) greater termweight than b.

Using this comparator will tend to result in multiple calls to recalc_maxweight() for each of the subqueries (we use it with nth_element which should be O(n)) - perhaps it'd be better to call recalc_maxweight() once and then sort on that.
