You must apply
limit()to the cursor before retrieving any documents from the database.
limit()to maximize performance and prevent MongoDB from returning more results than required for processing.

A negative limit is similar to a positive limit but closes the cursor
after returning a single batch of results. As
such, with a negative limit, if the limited result set does not fit
into a single batch, the number of documents received will be less than
the specified limit. By passing a negative limit, the client indicates
to the server that it will not ask for a subsequent batch via
Sorting on fields that contain duplicate values may return an inconsistent sort order for those duplicate fields over multiple executions, especially when the collection is actively receiving writes.
The easiest way to guarantee sort consistency is to include the
_id field in your sort query.
