Is possible to use Lucene queries with ElasticSearch?

I wonder if it’s possible to use a Lucene query directly

You cannot use an instance of org.apache.lucene.search.Query with the Elasticsearch backend, no.

You can pass a query string with the Lucene syntax to Elasticsearch, though:

• either with the simpleQueryString predicate (it offers a different syntax from your example)
• or with a native Elasticsearch predicate where you’ll pass the JSON for the queryString query. We will add an API for that predicate in Hibernate Search at some point, but that’s not implemented yet ([HSEARCH-4563] - Hibernate JIRA).

if there is any sort of “query converter” implemented in HIbernate Search 6.

There is not, and there never will be. We tried that in Hibernate Search 5 and it was a nightmare to maintain. 0/10, won’t do it again.
