Elasticsearch / Kibana-我可以在脚本查询中使用查询结果来执行计算吗？

Question

我正在尝试创建查询以输出比率。第一个数字是OutageTime字段的总和。第二个数字是脚本字段。

这是我的地图：

                }
              }
            }
          }
        }
      },

                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }

                  }
                }
              },
              "OutageTime": {
                "type": "long"
              },
              "RequestedDateTime": {
                "type": "date"
              },
              "SearchRangeMinutes": {
                "type": "long"
              },
              "host": {
                "type": "text",
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              },
              "isServiceAvailable": {
                "type": "boolean"
              },
              "tags": {
                "type": "text",
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              }
            }
          }
        }
      }
    }

这是我的查询：

    GET index-*/_search
    {
      "_source": {
                  "includes": [ "RequestedDateTime"]
      },
      "aggs":{  
             "TotalOutageTimSeconds":{  
                 "sum":{  
                     "script":"doc['OutageTime'].value"
                 }
              }
          },
      "sort":[{
        "RequestedDateTime":{
          "order":"asc"
        }
      }],
      "size": 1, 
      "script_fields":{
        "AvailabilityRatio":{
          "script":"(1 - (TotalOutageTimSeconds  / (new Date().getTime() - doc['RequestedDateTime'].value.getMillis()) / 1000))"
        }
      }
    }

基于我的映射和查询，是否可以在脚本化查询（AvailabilityRatio）中使用聚合结果（TotalOutageTimSeconds）？
