注：本文基于Elasticsearch 6.1.2编写

最近遇到这样一个需求，要通过Elasticsearch将Doc根据A字段降序，然后获得B字段的值，最终根据B字段的值再去做[Pipeline Aggregation][1]。

先尝试了[Max Aggregation][2]，但是Max Aggregation只能获得A字段的最大值。

然后尝试了[Top Hits Aggregation][3]，但是Top Hits Aggregation的结果无法被Pipeline Aggregation使用。

最终尝试[Scripted Metric Aggregation][4]成功。下面举例说明
