Marking this out of date as I'm not sure if it was always possible, but it is now.
We could open a follow-up issue to make it an easier looking API, if someone comes with a concrete proposal.

For the record I've just reviewed a benchmark which does use the setCriteriaQuery like suggested by Emmanuel:
Query q = fts.getSearchFactory()
.buildQueryBuilder()
.forEntity(Book.class)
.get()
.keyword()
.onField("authors.name")
.matching("author" + authorId)
.createQuery();
Criteria fetchAuthors = fts.createCriteria(Book.class).setFetchMode("authors", FetchMode.JOIN);
List<Book> result = fts.createFullTextQuery(q, Book.class).setCriteriaQuery(fetchAuthors).list();It works.

Isn't it what FullTextQuery#setCriteriaQuery already provides?

I would like to have the fetch join strategy supported for all entities related to the indexed entity and not just for the ones that are IndexedEmbedded.

In Hibernate search, the related entities marked using @IndexedEmbedded are now getting lazy fetched which is causing unnecessary queries to be generated. It would be useful if fetch joins can be used for better performance.
