title: maximum limit for MongoDB 2.6 sort query
body: <p>sorting 2 millions of records using mongo sort is possible or not?</p>
  
  <p>From the MongoDB Documentation, it is clearly mentioned that "When the sort operation consumes more than 32 megabytes, MongoDB returns an error."</p>
  
  <p>But I have a requirement to sort huge number of records. How to do it?</p>
