Question

让我从搜索开始，但找不到我要寻找的特定答案。我有文档，它们存储在芒果或Couchbase之类的NSQL数据库中，并且这些文档有一个对象，该对象又可以容纳另一个对象或对象数组。文档中的每个对象都有一个唯一的GUID，我希望能够找到该GUID并返回完整路径。如果我将guid的搜索路径固定在哪里，那么我已经成功地做到了，但是我希望有一种方法可以不受预定义的路径和子级别限制。

这是一个样本

Couchbase通过“关键字”（https://docs.couchbase.com/server/5.5/n1ql/n1ql-language-reference/collectionops.html#collection-op-within）解决嵌套搜索。您尚未指定正在使用的数据库，所以建议您搜索类似的运算符。

在对象中查找属性并返回完整路径
