我想得到满足一定条件的群体数量.在SQL术语中,我想在Elasticsearch中执行以下操作.

SELECT COUNT(*) FROM
(
   SELECT
    senderResellerId,
    SUM(requestAmountValue) AS t_amount
   FROM
    transactions
   GROUP BY
    senderResellerId
   HAVING
    t_amount > 10000 ) AS dum;

到目前为止,我可以通过term Aggsel对senderResellerId进行分组.但是当我应用过滤器时,它不能按预期工作.

{'country': 'France', 'collected': '2018-03-12', 'active': true}
{'country': 'France', 'collected': '2018-03-13', 'active': true}
{'country': 'France', 'collected': '2018-03-14', 'active': false}
{'country': 'Canada', 'collected': '2018-02-01', 'active': false}
{'country': 'Canada', 'collected': '2018-02-02', 'active': true}

假设我有这个结果集,我想按国家对它们进行分组.按国家对它们进行分组后,结果如下:

{'country': 'France', 'collected': '2018-03-14', 'active': false}
{'country': 'Canada', 'collected': '2018-02-02', 'active': true}

但是,我要排除结果,其中最后一排active是false(同一个国家的老行可以是真或假并不重要,只要最后一行等于true),我怎么能在elasticsearch做到这一点？这是我的查询:

                                    "order": "desc"
                                }
                            }
                        ]
                    }
                } …
