title: MongoDb Range Query on ObjectId
body: <p>I had like to know if somebody knows if it is possible to query the _id field with a
  query like this : </p>
  
  <pre><code>{$lte : ObjectId(....) , $gte : ObjectId(...)
  </code></pre>
  
  <p>, instead of </p>
  
  <pre><code>{$in : [ObjectId( )...lots of ObjectId.....]}
  </code></pre>
  
  <p>and if there is a gain in performance (i think so..)</p>
  
  <p>Thanks</p>
