title: Possible to find a object in a array, that is in a object of arrays?
body: <p>I have a schema like looks like this:</p>
  <pre><code> parent: [{
                  year: Number,
                  kind: String,
                  child:  [{age: Number, value: Number}]
              }],
  </code></pre>
  <p>My query looks like this:</p>
  <pre><code>myDB.findOne({'parent.year': year, 'parent.kind': kind})
  .where('parent.child.age').equals(age)
  </code></pre>
  <p>As expected, I get the correct parent element. But that parent element, as you can see, has an array with children. Is there any way mongoose can give me a single object in the child array? Or do I need to find it myself?</p>
