title: find the document from sub array?
body: <p>I have a collection with documents that look like this:</p>
  
  <pre><code>"awards" : {
      "oscars" : [
          {"award": "bestAnimatedFeature", "result": "won"},
          {"award": "bestMusic", "result": "won"},
          {"award": "bestPicture", "result": "nominated"},
          {"award": "bestSoundEditing", "result": "nominated"},
          {"award": "bestScreenplay", "result": "nominated"}
      ],
      "wins" : 56,
      "nominations" : 86,
      "text" : "Won 2 Oscars. Another 56 wins and 86 nominations."
  }
  </code></pre>
  
  <p>What query document would we use in a <code>find()</code> command to return all movies in the <code>my_collection</code> collection that either won or were nominated for best picture?</p>
