title: Elasticsearch query with NEST don't work
body: <p>I'm using Microsoft SQL Server Management Studio and ElasticSearch 2.3.4 with ElasticSearch-jdbc-2.3.4.1, and i linked ES with my mssql server. Everything works fine, but when i make a query using NEST on my MVC program the result is empty. When i put an empty string inside my <code>search</code> attribute i get the elements, but when i try to fill it with some filter i get an empty result. Can someone help me out please? Thanks in advance.</p>
  
  <p><strong>C#:</strong> </p>
  
  <pre><code>const string ESServer = "http://localhost:9200";
  ConnectionSettings settings = new ConnectionSettings(new Uri(ESServer));
  settings.DefaultIndex("tiky");
  settings.MapDefaultTypeNames(map =&gt; map.Add(typeof(DAL.Faq), "faq"));
  ElasticClient client = new ElasticClient(settings);
  
  var response = client.Search&lt;DAL.Faq&gt;(s =&gt; s.Query(q =&gt; q.Term(x =&gt; x.Question, search)));
  
  var result = response.Documents.ToList();
  </code></pre>
