my test code :
Client client = ElasticSearchUtils.getClientInstance();
QueryBuilder qb1 = new TermQueryBuilder("title", "this");
SearchResponse response = client.prepareSearch().setQuery(qb1).execute().actionGet();
SearchHits hits = response.getHits();
if(hits!=null){
for(SearchHit hit :hits){
System.out.println(hit.getSource().get("description"));
}
}
