我有一个弹性搜索查询，它从查询结果中获取聚合。聚合工作正常，因为如果我选择从“女性时尚”类别获得所有颜色为金色的礼服。
聚合工作正常，因为它只返回黄金色。但从逻辑上讲，我们需要聚合中的所有颜色。
在前端过滤器上，我们直接显示聚合请求中的记录。现在在有人选择“黄金”颜色的前端，它向下钻取并移除所有其他颜色过滤器，只显示金色。
我们需要以某种方式避免聚合中的颜色以显示所有结果。

经过大量文档后，有一种称为后置过滤器的东西可以某种方式解决这个问题。我试过用它但有点复杂。有没有人有过这方面的经验。
我使用全局聚合更新了查询： 我尝试过使用全球聚合，但它现在显示了elasticsearch中的所有品牌，我想展示与该类别产品相关的品牌。
