    Description

      I have a field in my index that is lowercased after the KeywordTokenizer. I wish to do grouping on this field. It is a distributed index.

      This works fine in Solr 4.9.1 running on Java 8.

      When I try the distributed grouping request (with the same schema) on Solr 5.2.1, it fails, with this exception:

      java.lang.IllegalStateException: unexpected docvalues type SORTED_SET for field 'ip' (expected=SORTED). Use UninvertingReader or index with docvalues.

      If I make the same request directly to one of the shards on 5.2.1, it works. If I create a copyField to a field using StrField with docValues, the distributed request works ... but then I lose the lowercasing.
