elasticsearch,Json,Json 如何检查嵌套类型elasticsearch对象中缺少的键？
我在一个案例中收集了一些常规信息和数据库信息（db2、oracle、sybase、informix），这些信息以键值对json格式的文档形式存在 我也有一些规则来检查上面的文档是否满足特定的规则，如果满足，则返回特定的文档进行分析 这是医生Json 如何检查嵌套类型elasticsearch对象中缺少的键？,json,

名称雅典娜Oracle数据库opencursors小于建议值4000opencursors不存在时的文档
因此，只有在以下匹配的情况下，上面的doc/twitter/tweet/1
才会作为结果返回
If（name==“Athena”）&&（db.@类型包含“Oracle”关键字）
和（如果（（“open_cursors”@value<4000）或（“open_cursors”未在“db.oracle_props@name”下找到）
下面是与上述文档匹配但缺少最后一个条件的搜索查询（display doc）/twitter/tweet/1”，即使在“db.oracle\u props@name”下缺少“open\u cursors”键
我会再试一次，参考你的和
如果我正确理解您的要求，我将建立一些示例文档，这些文档应该与我的评论正确匹配，或者不正确匹配：

因此，我们有3个应该返回的文档（ID1,2,3
）
我发现的解决方案似乎很复杂，也许其他人可以提供一个更简单的方法来解决这个问题
为了能够使用
谢谢。这正是我需要的。@Thorsten，为什么我们需要在嵌套筛选器之前使用bool.must？我们可以在OR筛选器之后立即使用嵌套筛选器吗？谢谢，没有它应该可以工作，你是对的。我已经更新了答案。
