HI,  
I am using elasticsearch 5.3 and need to calculate top 50 client\_ip and order by **1m-peak-value** in one day .  
like this , I try to use a 1 size date\_histogram to get the peak value,

```auto
"aggs": {
          "client_ip": {
            "terms": {
              "field": "ClientIp", 
              "order": {"timeline>pktlen": "desc"},
              "size": 50
            },
            "aggs": {
              "timeline": {
            	"date_histogram": {
            		"field": "ts",
            		"interval": "1m",
            		"order": {"pktlen": "desc"},
                    "size": 1
            	},
            	"aggs": {
            		"pktlen": {
                		"sum": {
                			"field": "PktLen_Sum"
                		}
            		}
            	}
              }
          }
        }
      }

```

Sadly, it gets two errors

- Terms buckets can only be sorted on a sub-aggregator path that is built out of zero or more single-bucket aggregations within the path and a final single-bucket or a metrics aggregation at the path end

- Date histogram not support size

So how can I get the top 50 client\_ip ordered by peak value
