I'm using spring-data-mongodb-1.2.0.RELEASE.
I have two classes A and B where B has a reference to A and it is annotated with @DBRef.
Since I'm quering for all instances of B that are refering to a certain A:
I need it to be indexed.
After the first insertion of a B instance into MongoDB an index should be created.
As can be seen below it doesn't:

Does anyone know how can I create such an index ?

Code:
@Document(collection = "a")
public class A {
@Id
public String id;
/** The TicketGrantingTicket this is associated with. */
@Field
public String name;
public A(String id, String name) {
this.id = id;
this.name = name;
}
}Code:
@Document(collection = "b")
public class B {
@Id
public String id;
@Field
public String name;
@DBRef
@Indexed
public A a;
public B(String id, String name, A a) {
super();
this.id = id;
this.name = name;
this.a = a;
}
}Code:
B fromDB = mongoOperations.findOne(Query.query(Criteria.where("a.$id").is(a1.id)), B.class);After the first insertion of a B instance into MongoDB an index should be created.
