在Objectify中由多个祖先查询

Question

Is it possible to load() entities from multiple ancestor.
I have two Kinds 1- user, 2- post User is ancestor of post

I know how to apply ancestor query for single user like this ofy().load().type(Post.class).ancestor(user1).list();
But how can apply query for multiple ancestors ?
Maybe something like this
ofy().load().type(Car.class).ancestors(user1,user2).list();

Is it possible how can I do that if not what I do to achieve this ?

Answer 1

It is not possible. Datastore not supports multi ancestor queries as well as OR operator. You will need to make two separate queries for that.
