22 A QueryFilter spawns a result set that can be used to filter the
23 results of another query. The effect is very similar to adding a
24 required clause to a BooleanQuery -- however, a QueryFilter caches its
25 results, so it is more efficient if you use it more than once.

33 Constructor. Takes one hash-style parameter, "query", which must be an
34 object belonging to a subclass of KinoSearch1::Search::Query.
