On second reading, I think you want runtime polymorphism on `@IndexedEmbedded`? If so, then that’s not supported (yet).

See [java - lucene / hibernate search - Cannot search by fields in subclass in collection - Stack Overflow](https://stackoverflow.com/q/56100751/6692043) ; there’s a suggested workaround, but I’m not sure how you would implement it in Search 6. Maybe [@IndexingDependency for abstract Method](https://discourse.hibernate.org/t/indexingdependency-for-abstract-method/4996/) will be relevant to you, too.
