Elasticsearch 消除重复结果

Question

给定以下文档：

name: Peter, enterTime: 2022-01-27
name: Peter, enterTime: 2022-01-28
name: Peter, enterTime: 2022-01-29
name: Jenny, enterTime: 2022-01-29
name: Jenny, enterTime: 2022-01-30
name: Peter, enterTime: 2022-01-31
name: Peter, enterTime: 2022-02-01
name: Jenny, enterTime: 2022-02-02
name: Jenny, enterTime: 2022-02-03

我想编写一个elasticsearch查询，如果下一个结果相同，则按名称对结果进行分组，并且仅显示第一个结果。 我期待的结果：

name: Peter, enterTime: 2022-01-27
name: Jenny, enterTime: 2022-01-29
name: Peter, enterTime: 2022-01-31
name: Jenny, enterTime: 2022-02-02

我尝试过聚合查询和折叠，但到目前为止我失败了。任何提示将不胜感激。
