Elasticsearch

简单地将脚本移到聚合上怎么样？

{   "query": {      "filtered": {         "query": { "match_all": {}         },         "filter": { "and": [    {       "exists": {          "field": "time.new_time"       }    },    {       "exists": {          "field": "time.first_alert_time"       }    } ]         }      }   },   "aggs": {      "avg_timedifference": {         "avg": { "script" : "Math.ceil(doc['time.new_time'].value - doc['time.first_alert_time'].value)"         }      }   }}
