title: Partial update elastic search NEST 2.x
body: <p>how can partial update a record in using NEST2?</p>
  
  <p>I'm looking for an analog request:
      POST /erection/shop/1/_update
      {"doc": {"new":"0"}}</p>
  
  <p><strong>without recreating</strong> a new record. unfortunately I did not find anything about the updates in www.elastic.co/guide/en/elasticsearch/client/net-api/current/index.html</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <pre><code>var updateResponse = es.Current.Update&lt;MyDocument, MyDocument&gt;   (DocumentPath&lt;MyDocument&gt;.Id(2), descriptor =&gt; descriptor
       .Doc(new MyDocument
       {
           name = "new name"
       }));
  </code></pre>
  
  <p>I run this code, but it is fully updated the whole document.</p>
