指定返回字段，查询方式，

SearchResponse response = client.prepareSearch("sb").setTypes("sb")                    .setQuery(query).setFrom(0).setSize(500)                    .setExplain(false)                          .addFields(new String[]{"cphm1","jcdid","cplx1","tpid1","tgsj","cdid"})                    .execute().actionGet();```**结果获取方式：**    //指定返回字段时的结果获取方式------begin---------Map<String, Object> map = new HashMap<String, Object>();List<Map> listresult = new ArrayList<Map>(); for(final SearchHit hit:response.getHits()){               final Iterator<SearchHitField> iterator = hit.iterator();                while(iterator.hasNext()){             final SearchHitField hitfield = iterator.next();             map.put(hitfield.getName(),hitfield.getValue());             System.out.print(hitfield.getName()+"=="+hitfield.getValue()+"-----");               }               listresult.add(map);             System.out.println();} for(final Map m:listresult){// System.out.println(m.get("jcdid")+"--"+m.get("cphm1")+"--"+m.get("tpid1")+"--"+m.get("tgsj")); }**普通查询方式**SearchResponse response = client.prepareSearch("sb").setTypes("sb").setQuery(query).setFrom(0).setSize(500).setExplain(false).execute().actionGet();结果获取方式：

SearchHits hits = response.getHits();
for (int i = 0; i < hits.getHits().length; i++) {
System.out.print(“主键值：”+hits.getAt(i).getId()+”—>”);
System.out.print(hits.getAt(i).getSource().get(“cphm1”) + “—”);
System.out.print(hits.getAt(i).getSource().get(“cplx1”) + “—”);
System.out.print(hits.getAt(i).getSource().get(“jcdid”) + “—”);
