title: How can I use Mongo $index so the query would NOT use any index
body: <p>this question is somewhat strange, but I bumped onto it in a current implementation of mine:</p>
  
  <p>I want to privilege inserts over everything in my application and it came to my mind that the command $hint could also be used to let mongo NOT use an index.</p>
  
  <p>Is that possible? is that a sound question, considering what $hint is supposed to do?</p>
  
  <p>Thanks</p>
