Subject [jira] [Commented] (LUCENE-3191) Add TopDocs.merge to merge multiple TopDocs
Date Tue, 28 Jun 2011 06:38:17 GMT


Uwe Schindler commented on LUCENE-3191:

I haven't tracked this issue to understand whats going on here, but you cannot pass BytesRefs
to If this code is ever reached (and looking at the test i wrote for this
damn thing, its unclear if this code is even necessary?!)

The code is necessary once you cross segments during compare. Maybe the index in the tests
is so small that it never has multiple segments.
