脚本化指标聚合顺序 [英] Scripted Metric Aggregation order

问题描述

在elasticsearch 1.5.0中，我尝试使用scripted_metric结果对聚合存储桶进行排序/排序，但收到以下错误：

In elasticsearch 1.5.0, I try to sort/order the aggregation bucket using scripted_metric result,but receive bellow error:

AggregationExecutionException [无效的术语聚合顺序路径[ custom_script]。条款存储桶只能在子聚合器路径上排序，该子聚合器路径是由路径中的零个或多个单存储桶聚合以及路径末端的最终单个存储桶或指标聚合构成的

AggregationExecutionException[Invalid terms aggregation order path [custom_script]. 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

有什么办法解决这个问题？

is any way to solve this issue?

我的查询是这样的：

"aggs": {
    "mygroup": {
      "terms": {
        "field": "customername",
        "order": {
          "custom_script": "asc"
        }
      },
      "aggs": {
        "custom_script": {
          "scripted_metric": {
            ...
          }
        }
      }
    }
  }
