I'm attempting to upgrade my project to Lucene 6.0, and have run into an issue with sorting my results. My documents have a timestamp field that was previously a StoredField with NumericType: Long. I've converted it to a LongPoint, which seems to work fine for range queries.
My problem is that trying to sort search results with a SortField of type Long now doesn't seem to work with a LongPoint field. I get an IllegalStateException "unexpected docvalues type NONE for field 'timestamp' (expected=NUMERIC). Use UninvertingReader or index with docvalues." I'm guessing the sorter hasn't been updated to work with PointValues yet, but I just wanted to check with the mailing list to see if anyone else has found a way to do results sorting under 6.0.
