springdata elasticSearch 查询高亮显示

postman 中请求 ：http://localhost:9200/document/_search

用post 请求：

{
	"query":{
		"multi_match":{
			 "query": "朗逸",
    		 "fields": ["desc"]
		}
	},
	
	"from": 0, 
	"size": 100,
	"sort": [
		{"craetetime":"asc"}
    ],
	"highlight": { 
			"require_field_match": false, 
			"fields": { 
				"title": { "pre_tags": [ "<font color='red'>" ], "post_tags": [ "</font>" ]} ,
				"desc": { "pre_tags": [ "<font color='red'>" ], "post_tags": [ "</font>" ]}
				}
		}
}

返回结果
