Hello,

You probably forgot to set a target on your search query. By default Hibernate Search targets all indexed entities, which explains the message about the "Staff" index missing these sort fields.

Instead of this:

session.createFullTextQuery( query )

Do this:

session.createFullTextQuery( query, RegistryReference.class )

Please tell us if this solves your problem, so I can close this ticket.

Note that we monitor the tag hibernate-search on stackoverflow; should you encounter a problem again, you can always ask a question there.
