一，最终实现：查询条件及查询结果如下图所示
需要实现：分组，求和，聚合后排序，总计，分页
二， 需求分析：关于分组维度
es数据主键为：日期（年月日）+采购组织+采购组+门店
统计维度：可根据是否选择门店，按日或按月统计可分为四种情况
日+采购组织+采购组；采购组织+采购组；日+采购组织+采购组+门店；月+采购组织+采购组+门店；
按正常es多条件分组求和处理方式很麻烦，可参考网上写法。可以转变思路，把每个维度拼接成一个字段，即新增四个字段，多条件分组统计转化为单条件分组统计，实现起来会简单的多。如下图所示：
三，代码实现
关于聚合
难点在于聚合统计，及聚合统计后再合计
关于排序
聚合求和的字段排序与不需要聚合求和的字段区分开来，前者可以直接应用es特性直接排序，后者排序，对处理之后的数据lis排序，java特性排序对list排序
关于分页
es无法复杂聚合后排序，对处理之后的数据进行伪分页排序，并不是真正意义上的排序，可以减轻前端压力，对于后台是对所有的数据伪分页。

}聚合求和及聚合合计字段处理
1.注意维度下数据量，如果大于10000条，多余的数据不会计入聚合统计，如下图说明
2.注意聚合求和和聚合合计的层级关系，聚合统计字段以子聚合关联，聚合合计字段与分组维度一个层级
/**
* 统计，排序
* 分组size含义：需要返回分组后的个数；如按某维度分组，10个结果，size=2，只会返回两个结果。应该小于10000
* 分组size测试：
* 条件：全部100家门店，日期5月份，包含门店，按日维度统计
* 结果：查询总量：19703 1，size>10000，程序异常；2，size=10000(查询时长大概30s)，实际只取前10000条数据聚合返回，导致数据不准
* 处理：如果size>10000，抛业务异常，缩小范围
