Dear All.

Hi @rameshkr1994,

I believe what you are looking for is aggregations. I am not sure, but you should explore Terms Aggregation.

Link for reference :
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html

An Example Query :

GET <index_name>/_search?_source=false
{
  "query": {
    "bool": {
      "filter": [{
          "term": {
            "name": "ram"
          }
        }]
    }
  },
  "aggs": {
    "group_by_id": {
      "terms": {
        "field": "id",
        "size": 1000
      },
      "aggs": {
        "top_hits": {
          "top_hits": {
            "size": 100,
            "_source": ["cnt", "marks"]
          }
        }
      }
    }
  }
}

The above is just a adhoc query. You may need to modify or tweak it a little.

Hope that helps.

Regards,
Somnath

}
}
}
}
}

response :-(ERROR)

{
"took": 1,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 0,
"relation": "eq"
},
"max_score": null,
"hits":
},
"aggregations": {
"group_by_id": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,

still not getting this solution!!

as per your gouide i tried ?filter with term is not working here !! if change here filter and term with must and match then result is fetching but previous output is coming ?

As mentioned earlier, The query would require some tweaking before using it. I am assuming you are using the right keys.

Someone should help out in regards to this. My Apologies.
