推荐答案

我找到了它.只需执行以下操作即可:在路径中使用group = true或从过滤器结果中选择它. 以及一个reduce函数，用于从地图中返回所有值.您还可以添加开始键="2014/10/31"和结束键="2014/10/31".

I found it . Just do : group = true in the path or select it from the filter result . and a reduce function to return all the values from the map. also you can add the start key = "2014/10/31" and end key= "2014/10/31".
