elasticsearch条件查询高亮实现restful api以及java代码实现

restful api实现：

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

{

  "query":{

     "match":{"title":"战"}

  },

  "_source":{

    "include":["title","price"]

  },

  "highlight":{

      "fields":{"title":{}}

   }

}

java代码实现：

/**
 * 条件查询高亮实现
 * @throws Exception
 */
@Test
public void searchHighlight()throws Exception{
	SearchRequestBuilder srb=client.prepareSearch("film").setTypes("dongzuo");
	HighlightBuilder highlightBuilder=new HighlightBuilder();
	highlightBuilder.preTags("<h2>");
	highlightBuilder.postTags("</h2>");
	highlightBuilder.field("title");
	SearchResponse sr=srb.setQuery(QueryBuilders.matchQuery("title", "战"))
			.highlighter(highlightBuilder)
			.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());
		System.out.println(hit.getHighlightFields());
	}
}

运行输出：

{"price":"38","title":"战狼2"}

{title=[title], fragments[[<h2>战</h2>狼2]]}

{"price":"55","title":"星球大战8：最后的绝地武士"}

{title=[title], fragments[[星球大<h2>战</h2>8：最后的绝地武士]]}
