Sometimes you really want to get some other objects than the one you are querying. Example from link queries:

• I want to find all Persons with a dog that is brown and called Fluffy.

That is currently only possible when querying Persons:

RealmResults<Owner> r2 = realm.where(Owner.class)
.equalTo("dogs.name", "Fluffy")
.findAll()
.where()
.equalTo("dogs.color", "Brown")
.findAll();

With a collect operator you could do instead:

RealmResults<Owner> = realm.where(Dog.class)
  .equalTo("name", "Fluffy")
  .equalTo("color", "Brown")
  .findAll()
  .collectAll(Owner.class, "owner") // Dog needs a owner field

Overriding findAll could also be an option, although I probably like the collect operator more as it is also a well known functional method.

RealmResults<Owner> = realm.where(Owner.class)
  .equalTo("name", "Fluffy")
  .equalTo("color", "Brown")
  .findAll(Owner.class, "owner);

What do you think @realm/java

EDIT: Or maybe the above is just a symptom that the current query language are missing some features since findAll already is a collect statement, so we should fix that instead.
