We are actually in the [slow] process of trying to simplify the DV
APIs (calling it DV 2.0 for now...), at this branch:
https://svn.apache.org/repos/asf/lucene/dev/branches/lucene4547
If you have the itch, feel free to check it out and iterate! There
are lots of changes there, roughly summari
I think you just forgot to call iw.addDocument(doc)?
Typically one needs DocValues in a Collector or a FieldComparator or
Filter or a Similarity Scorer, etc., which already operate per-segment
and provide you an AtomicReaderContext from which you can get the
AtomicReader to lookup DocValues from .
