      Bug reports should generally be accompanied by a test case!


      I recently upgraded from 5.3.0.Final to 5.6.0.Alpha3, following the migration guide.

      As soon as I did I noticed that sorting HS queries by "id" field (id is the name of the property that I have annotated with @Id) simply fails silently. I.e., no exception is thrown, but results are not sorted by id. This property is of type Long, which means that the Lucene field is of type NUMERIC.

      I then saw the following warning emitted by Hibernate whenever I run my query:

      HSEARCH000289: Requested sort field(s) id are not configured for entity type com.fivoosh.entities.Applicant mapped to index com.fivoosh.entities.Applicant, thus an uninverting reader must be created. You should declare the missing sort fields using @SortableField.

      Ok, I added the @SortableField annotation and reindexed, then tried running the query again. This time I got an exception:

      Caused by: java.lang.IllegalStateException: unexpected docvalues type SORTED for field 'id' (expected=NUMERIC). Use UninvertingReader or index with docvalues.

      I tried changing the type in my SortField but alas - the SortField.Type enum doesn't contain a value named "SORTED".
