Adrien Grand updated LUCENE-6207:
---------------------------------
Attachment: LUCENE-6207.patch
The bug is that doc values terms enums assume that nothing else is going to use
the underlying dv instance at the same time. Here is a patch that makes the
attached test case pass. I also added tests to the base dv format test case and
to the Lucene50 one to test the compressed terms dict.
> Multiple filtered subsets of the same underlying index passed to
> IW.addIndexes() can produce an index with bad SortedDocValues
