title: Get specific part of document
body: <p>I'm trying Mongo db and I wonder if it's possible to only get a specific part of a document?</p>
  
  <p>For example I have:</p>
  
  <pre><code>{
    "name" : "MongoDB",
    "info" : { x : 203, y : 102 }
  }
  </code></pre>
  
  <p>and I only want the content of <code>info</code>.  </p>
  
  <p>The closest I found is <code>db.collection.find({}, { info: 1 })</code>  but this returns me <code>{ "info" : { x : 203, y : 102 } }</code> when I only need <code>{ x : 203, y : 102 }</code>.</p>
