Creating queries with complex 'and' and 'or' combinations

According to QueryBuilder documentation, we can define the order of logical operations using implicit and(). However, this implementation does not allow us to create complex conditions, such as (A and B) or (C and D). This comment provides a workaround, but having Realm-like chainable queries would be much nicer. Is changing existing QueryBuilder mechanics planned in future versions?

Yes, the query API subject to changes and this will be solved, of course. 😃 P.S.: if you don’t have a very big amount of entities, a more convenient work around are query filters.

3.0.0-alpha1 has a preview of a new Query API that supports nested conditions. We welcome feedback! https://docs.objectbox.io/#v-3-0-0-alpha1-2020-03-09 https://docs.objectbox.io/queries#new-query-api

An example for (A and B) or (C and D):

List<User> query = box.query(
        User_.propA.equal(x).and(User_.propB.equal(y))
                .or(User_.propC.equal(s).and(User_.propD.equal(t)))
).build().find();
