You need to use skip and limit

With skip, you set the number of documents that you will skip.

With limit, you set the page size.

Example:

db.test.find({}).skip(10).limit(10)

Would return the 2nd page in 10 document page sizes.

A skip(20).limit(10), would return the 3rd page…

Most of the times you should use this methods over ordered data.
