I've multiple entities with foreign key associations.

Entity A

private String name;
@OneToMany
private Set<B> b;

Entity B

private String name;
@OneToMany
private Set<C> c;

Entity C

private String name;

Search can be performed on any name (A.name, B.name, C.name). If the search is performed on C.name, is it possible to return entities A and B as they are related to C?

can anyone answer my question, please?

you can get that by using hql.

and it goes as:

String query ="from A a, B b, C c
where c.name = a.name and c.name = b.name";

return getHibernateTemplate().find(query);

it will return too you all three objects. I dont know how to return only one object C

I'm planning to implement Hibernate Search.

Yes you can target just C, or any combination of A, B, C classes with the same query.
