Hi,  
I need a help on the query where I want to search by phone numbers and get latest date amount charged for that phone number  
my mapping structure is as follows

```
    "mappings":{
	"phone_list":{
		"properties":{
			"phone":{
				"type":"text"
			}
			"amount":{
				"type":"integer"
			}
			"date_timestamp":{
				"type":"text"
			}
			
		}
	}
}

```

I have performed a query which gives the latest date\_timestamp of a particular phone number . As follows

```
   {
      "query":{
    "match":{
          "phone":"1234567890"
        }
      },
      "aggs":{
          "latest_call_date&time":{
        "max":{
              "field":"date_timestamp"
            }
          }
    }
    }

```

Now how can I achieve the amount related to the date\_timestamp returned by aggregation function max.

Do you really need to use an aggregation? I think it's simpler to just sort the search results on `date_timestamp` and ask Elasticsearch for 1 hit. That one hit will then tell you everything you want to know about the most recent transaction for a given phone number.

```auto
GET test/_search
{
  "size": 1,
  "query": {
    "match": {
      "phone": "1234567890"
    }
  },
  "sort": [
    {
      "date_timestamp": {
        "order": "desc"
      }
    }
  ]
}

```

(By the way, I think `date_timestamp` should probably be mapped as a `date`?)

Hi Abdon,

I had resolved the query, the same way as you mentioned.

For sake of curiosity can we achieve the same by aggregation?

Maybe something with a [top hits](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-top-hits-aggregation.html) or a [max bucket](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-max-bucket-aggregation.html) aggregation could get you to what you need.
