Intersecting is possible, but BTrees and sets dont support ordering...
So I suppose that I have to convert search results to lists and to
merge/intersect them manually...
Or, given a set (containing final results set intersection) and a list
(containing TextIndexNG results, ordered by ranking), is it possible to
EFFICIENTLY get items of the set in the order in which they are stored
in the list ??
