elasticsearch之管道聚合

 "aggs": {

    "ip_count": {

      "terms": {

        "field": "ip",

        "order": {

          "_count": "asc"

        },

        "size": 0

      }

    },

    "sum_total": {

      "sum_bucket": {

        "buckets_path": "ip_count._count"

      }

    }

  }

如何只显示管道聚合结果，不显示中间结果
