title: How should I store boolean values in mongodb?
body: <p>I see three main possibilities for storing boolean information in mongodb:</p>
  
  <ol>
  <li>0 or 1 as a String</li>
  <li>0 or 1 as a Number</li>
  <li>True or False as a Boolean</li>
  </ol>
  
  <p>What are the advantages/disadvantages of each method in terms of storage space used and the speed of queries?</p>
