I'm new to Hibernate Search. I've a manyToMany relation and want to perform search. They are defined in 3 tables - Person, Role, PersonRoles. Where do I use the @IndexedEmbedded and @ContainedIn annotations if I want to search by role and get a list of persons?

Person
@OneToMany(mappedBy="person",fetch=FetchType.LAZY)
private Set roles;Role
@OneToMany(mappedBy="role",fetch=FetchType.LAZY)
private Set persons;PersonRole
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="PERSON_ID")
private Person person;

@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="ROLE_ID")
private Role role;
