Hi @Ondrej_Laga

Thanks for reaching out. There were no such plans. Hibernate Search is backed by the QueryDSL ( [QueryDSL | Reference](https://www.elastic.co/docs/reference/query-languages/querydsl) ) and lookup joins you mentioned are part of the ESQL (as far as I can tell…). Unless there’s an alternative in the QueryDSL adding that wouldn’t be easy, and I’m not sure we’d want to go that route.
