Currently the type passed to forEntity() is not used to limit the query results to that type. This can be surprising when doing queries like this:

Query query = queryBuilder
    .forEntity( Animal.class )
    .get()
    .all()
    .createQuery();

This query will return all instances of all indexed entities instead of only Animal instances as one might expect. Instead the type has to be restricted when creating the FullTextQuery:

 fullTextSession.createFullTextQuery( query, Animal.class );

The given entity type should be considered for type restriction implicitely, or there should be an option for this.

In a first step the documentation of forEntity() should describe the behavior.
