elasticsearch Elasticsearch中的动态日期间隔筛选器查询

我试图满足客户希望从elasticsearch中选择数据，并按可能更改的日期间隔分割文档计数的要求

[1] ：-我想选择在给定时间间隔（1.1.-31.1.）内开始/结束的所有文档

[2] ：-期望结果示例（kibana图表）

我有这样的文档，每个文档都有startDate和可选的endDate，这意味着请求尚未完成

到目前为止，我已经提出了以下Lucene查询，但是它们有硬编码的日期范围（这就是我试图摆脱的）

对于每个间隔，依此类推。这似乎工作得很好，但这是非常不切实际的。如果我们想要的时间间隔是一个月，那么我需要为这个月的每一天修改这些过滤器。如果有人想按月查看过去一年的数据，我需要创建一组新的查询

有更简单的方法吗？

您看过聚合范围或聚合直方图了吗？你还可以发布一些示例文档吗？@JBone谢谢你的提示。我已经添加了文档的整个示例。我已经查看了范围和聚合直方图，问题似乎是，我无法对每个桶应用过滤器。例如，如果我按日期聚合，间隔为1个月，我需要筛选在该间隔内有开始日期或结束日期的文档。查看我添加的lucene查询。您是否查看了聚合范围或聚合直方图？你还可以发布一些示例文档吗？@JBone谢谢你的提示。我已经添加了文档的整个示例。我已经查看了范围和聚合直方图，问题似乎是，我无法对每个桶应用过滤器。例如，如果我按日期聚合，间隔为1个月，我需要筛选在该间隔内有开始日期或结束日期的文档。请参阅我添加的lucene查询。
