The error suggests that the definition for listing_lastmodified was altered at some point without reindexing. I'm guessing that the field did NOT have docValues originally, then docValues was enabled. When the docValues setting for a field is changed, deleting the index and rebuilding it is required. In 6.4.0, simple field types like the TrieDoubleField used for tdouble have docValues enabled by default. Adding a field should never require a reindex, unless you want to populate that field in documents that have already been indexed. Thanks, Shawn
