A query that works fine in Solr 4.9.1 doesn't work in 5.2.1 with the same schema. The field that I am grouping on does not have docValues. I get this exception:
java.lang.IllegalStateException: unexpected docvalues type SORTED_SET for field 'ip' (expected=SORTED). Use UninvertingReader or index with docvalues. If I make a non-distributed request to a single shard on 5.2.1, or a distributed request on 4.9.1, it works fine. I created a copyField with docvalues, and I can do grouping on that field in 5.2.1. The original field uses KeywordTokenizerFactory, then it is lowercased. The copy with docValues is StrField. I need it to be lowercased in the groups (analyzed terms), so StrField isn't really what I'm after. This seems like a bug. I'm ready to file an issue in Jira, but thought it would be a good idea to mention it here first. Thanks, Shawn
