title: Can CQEngine query an object inside another object
body: <p>Does anyone know if CQEngine can query objects with in other objects? I would like to be able to query users, orders and products.</p>
  
  <p>Can this be done with CQEngine or would I need to flatten the objects?</p>
  
  <pre><code>public class User {
      public List&lt;Orders&gt; orders;
  }
  
  public class Orders {
      public List&lt;Products&gt; products; 
  }
  
  public class Products {
      public String name;
  }
  </code></pre>
