Yonik Seeley commented on LUCENE-2883:
--------------------------------------
Regarding weighting - function queries can contain normal queries, so anywhere
a function query is used, it must be weighted first.
bq. When ValueSource#getSort is called (which is only in 1 place really), we
can pass in the IndexSearcher, meaning the SortField can be 'weighted' then and
there.
Sort instances are like Query instances, and for many reasons should not be
bound to any particular searcher.
