Michael McCandless commented on LUCENE-3191:
--------------------------------------------
For 3.x, I think we should make an exception to back-compat and break the API (changing FieldComp.value(..)
to return <T> not Comparable; changing FieldDoc.fields from Comparable[] to Object[]).
I'll advertise the break in CHANGES.
> Add TopDocs.merge to merge multiple TopDocs
