title: Search object by value in array element in mongoose
body: <p>Say I have <code>updates</code> in database with this schema</p>
  
  <pre><code>{
  _id:Number
  isRead:[]
  }
  </code></pre>
  
  <p>Say I Have these data</p>
  
  <pre><code>{
      _id: 1, isRead:[1,2],
      _id:2, isRead:[3,4],
      _id:3, isRead:[1]
  }
  </code></pre>
  
  <p>when i use this query</p>
  
  <p><code>updates.find('isRead':1)</code> in mongo db it returns the needed result which is the first and the last
  But in mongoose i use the same query but it doesn't return any data,
  How can I modify my query in mongoose ?</p>
