title: How do I reverse sort natural in Morphia?
body: <p>I have a capped collection and I know I need to issue:</p>
  
  <pre><code>find().sort({$natural:-1})
  </code></pre>
  
  <p>to sort by most recent first. But how do I do this in Morphia?</p>
  
  <pre><code>query.order("-$natural"); // doesn't work
  </code></pre>
