Highlighting

Elasticsearch supports highlighting the parts of the response that caused the match. In the following query, the matches in the product_name field are highlighted:

#Highlighting
POST chapter7/_search
 {
   "query": {
     "match": {
       "product_name": {
         "query": "samsung"
        
       }
     }
   },
   "highlight": {
         "fields" : {
             "product_name" : {}
         }
     }
 }

The response to the preceding query is as follows:

{
   ....
   "hits": {
     "total": 2,
     "max_score": 0.7590336,
     "hits": [
       {
         "_index": "chapter7",
         "_type": "product",
         "_id": "AVsC7GDlF21JdiUIl1Q-",
         "_score": 0.7590336,
