You will not be able to do this directly with only the type column and the constraint that it must be one query. However there is (as always) a way to accomplish this.

To find documents of different types, you would need to have some type of additional value that, on average distributed the types out according to how you want the data back.

db.users.insert({type: 'A', index: 1})
db.users.insert({type: 'B', index: 2})
db.users.insert({type: 'A', index: 3})
db.users.insert({type: 'B', index: 4})
db.users.insert({type: 'A', index: 5})
db.users.insert({type: 'B', index: 6})

Then when querying for items with db.users.find(index: {$gt: 2, $lt: 7}) you will have the right distribution of items.

Though I'm not sure this was what you were looking for
