title: ElasticSearch POST with json search body vs GET with json in url
body: <p>According to the ES documentation, those 2 search request should get the same results:</p>
  
  <p>GET  </p>
  
  <pre><code>http://localhost:9200/app/users/_search?source={"query": {"term": {"email":"foo@gmail.com"}}}
  </code></pre>
  
  <p>POST  </p>
  
  <pre><code>http://localhost:9200/app/users/_search
  </code></pre>
  
  <p>Post body :  </p>
  
  <pre><code>{
      "query":  {
           "term": {
                 "email":"foo@gmail.com"
            }
      }
  }
  </code></pre>
  
  <p>But the first one gives no result while the second one gives me the expected result. I use ES version 0.19.10
  Did anybody else have the same behavior ? Is this a bug ?</p>
