title: Nested Object in Kibana visualize
body: <p>I have uploaded the JSON file in elasticsearch and my mapping contains of some nested objects.</p>
  
  <p>The problem is that, in Kibana, in visualize I can not see them</p>
  
  <p>This is my mapping:</p>
  
  <pre><code>"comments": {
      "type": "nested",
      "properties": {
          "count": {
              "type": "integer"
          },
          "data": {
              "type":"nested",
              "properties": {
                  "created_time": {
                      "type": "integer"
                  }
              }
          }
      }
  }
  </code></pre>
  
  <p>But in kibana when I insert <strong>comments.count</strong> I cannot see any result, but in Discover page, the <strong>comments.count</strong> field is exist! </p>
  
  <p>How can I search for this field? </p>
