elasticsearch数据列过滤restful api以及java代码实现

restful api实现：

POST http://192.168.1.111:9200/film/dongzuo/_search/

{

  "from": 0,

  "size": 2,

  "_source":{

    "include":["title","price"]

  }

}

Java代码实现：

/**
 * 数据列过滤
 * @throws Exception
 */
@Test
public void searchInclude()throws Exception{
	SearchRequestBuilder srb=client.prepareSearch("film").setTypes("dongzuo");
	SearchResponse sr=srb.setQuery(QueryBuilders.matchAllQuery())
			.setFetchSource(new String[]{"title","price"}, null)
			.execute()
			.actionGet(); // 分页排序所有
	SearchHits hits=sr.getHits();
	for(SearchHit hit:hits){
		System.out.println(hit.getSourceAsString());
	}
}

运行结果：
