So, I've tested this with

• Hibernate core 5.2.1.Final
• Hibernate core 5.2.6.Final

And it still occurs. I've been trying to roll back so I can test with Hibernate Search 5.5.6.Final but the dependencies between Spring, Hibernate ORM, Hibernate Search are getting too difficult to find a basic result.

Using luke with the same search, it return one row with the expected value for @Id.

I've added @DocumentId to my entity (along with @id, which is also a @MappedSuperclass. But this didn't help.

Looks like we need to wait for HSEARCH-2380 Open .
