> Hibernate Search allows you to optimize the fetching strategy for association by setting an optional {{Criteria}}:
> {code}
> Criteria fetchingStrategy = fullTextSession.createCriteria(Foo.class);
> fetchingStrategy.setFetchMode("foos", FetchMode.JOIN);
> fullTextQuery.setCriteriaQuery(fetchingStrategy);
> {code}
> This works fine for normal queries, however, in the case of projection queries and the use of {{FullTextQuery.THIS}} the fetch mode gets ignored. This is due to the fact that the {{ProjectionLoader}} internally uses {{MultiClassesQueryLoader}} in case {{FullTextQuery.THIS}} is projected. The logic from {{FullTextQueryImpl}} deciding which entity loader to use should really also be used within {{ProjectionLoader}}.
