title: DeleteByQuery using NEST and ElasticSearch
body: <p>I'm having a little difficulty getting NEST's DeleteByQuery method to work.</p>
  
  <p>Very simply the query never finds anything to delete, and I can't figure out why.  I'm using the same query to return records (using Search) and everything works as expected.</p>
  
  <pre><code>    private void Delete(MyClass someObject)
      {
          var response = elasticClient.DeleteByQuery&lt;MyClass&gt;(q =&gt; q                
              .Match(m =&gt; m.OnField(f =&gt; f.Guid).Equals(someObject.Guid))            
              );
      }
  </code></pre>
  
  <p>I've only just started using NEST, so I'm sure this is a pretty simple problem and I'm just being a little dim!</p>
  
  <p>Any help/suggestions much appreciated. </p>
