title: Elasticsearch sorting using java API
body: <p>I am trying to sort my document based on totalEmployee field, where index is <strong>index_db</strong> , the type is <strong>departments</strong> and a field is <strong>totalEmployee</strong> </p>
  
  <pre><code>QueryBuilder qb = QueryBuilders.matchAllQuery();
              SearchResponse response = client.prepareSearch("index_db").setTypes("departments")
                      .addSort(SortBuilders.fieldSort("totalEmployee").order(SortOrder.ASC)).setQuery(qb)
                      .setSize(100).execute().actionGet();
              for(SearchHit hits :response.getHits()) {
                  System.out.print("id = "+hits.getId());
                  System.out.println(hits.getSourceAsString());
              }
  </code></pre>
  
  <p>But I am getting error : </p>
