在弹性搜索中按字段模拟字段折叠/分组 [英] Simulating field collapsing/grouping by field in Elastic Search

推荐答案

可能不是你正在寻找的答案，但是据我所知，根据这个票，唯一真正的解决方法是在客户端选择较大的结果集和组。

Probably not the answer you're looking for but: As far as I know, and according to this ticket, the only real workaround is to select a larger result set and group on the client side.
