 Description   

Re:

http://docs.mongodb.org/manual/core/read-operations/#query-optimization

The optimizer iterates until it reaches 101 results from a single plan which is an ordered plan.

It does not stop at 101 results if they are spread across multiple plans nornif the plan producing the results is an unordered plan.

Thanks,

– Max
