We don't need to have a special SortedBytes ctor, right? The grouping ctors do take a DocValues.Type (joining, faceting etc can do the same). In the setNextReader method IR.docValues(groupField) is invoked. I'll also close LUCENE-3360 since it only couples the FC with IR. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
