Hi ,

In mysql i had query like

select \* from (select idx,machine,customer,FROM\_UNIXTIME(servertime) from Events where customer='MSP\_NH\_TEST' and machine in ('GERMAN','HFN-ENGINE','HFND100035','HFND100036') order by idx desc) as t group by machine;

Which gives me data of all latest records of user.

I tried in EL

{  
"size": 0,  
"query": {  
"match" : {  
"customer" : "BMW\_\_201700051",  
}  
},  
"aggs": {  
"machines": {  
"terms": {  
"field": "machine.keyword",  
"order": {  
"idx": "desc"  
}  
},

```
  }

```

}  
}

But am not getting expected result please someone help me.

Hi Avinash,

The simplest way I am thinking of is using [Field Collapsing](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-collapse.html):

```
{
  "query": {
    "match": {
      "customer.keyword": "MSP_NH_TEST"
    }
  },
  "collapse": {
    "field": "machine.keyword"
  },
  "sort": [
    {
      "idx": {
        "order": "desc"
      }
    }
  ]
}

```

Or using nested aggregations this should work as well:

```
{
  "size": 0,
  "query": {
    "match": {
      "customer.keyword": "BMW__201700051"
    }
  },
  "aggs": {
    "machines": {
      "terms": {
        "field": "machine.keyword"
      },
      "aggs": {
        "results": { 
          "top_hits": {
            "sort": [
              {
                "idx": {
                  "order": "desc"
                }
              }
            ],
            "size": 1
          }
        }
      }
    }
  }
}

```
