title: Using C# Nest API to get nested json data is not retrieving data
body: <p>I have the following json coming through the elasticsearch:</p>
  
  <pre><code>{
    "_index": "data-2016-01-14",
    "_type": "type-data",
    "_id": "AVJBBNG-TE8FYIA1rf1p",
    "_score": 1,
    "_source": {
      "@message": {
        "timestamp": 1452789770326461200,
        "eventID": 1452789770326461200,
        "eventName": "New",
        "Price": "38.34",
        "Qty": 100,
        "statistic_LatencyValue_ns": 1142470,
        "statistic_LatencyViolation": false,
        "statistic_LossViolation": false
      },
      "@timestamp": "2016-01-14T16:42:50.326Z",
      "@fields": {
        "timestamp": "1452789770326"
      }
    },
    "fields": {
      "@timestamp": [
        1452789770326
      ]
    }
  }
  </code></pre>
  
  <p>I'm using Nest to try to get the eventName data i created the class and marked the property:</p>
  
  <pre><code>public class ElasticTest
  {
      [ElasticProperty(Type = FieldType.Nested)] 
      public string eventName { get; set; }
  }
  </code></pre>
  
  <p>But the following query is returning 0 results, what am i doing wrong?</p>
  
  <pre><code>var result = client.Search&lt;CorvilTest&gt;(s =&gt; s
                      .From(0)
                      .Size(10000)
                      .Query(x =&gt; x
                      .Term(e =&gt; e.eventName,"New"))
                      );
                  var r = result.Documents;
  </code></pre>
