node.js - 将 QS 查询字符串转换为弹性云查询

Question

有什么方法可以将使用qs npm的查询字符串转换为弹性云查询字符串？哪个支持所有类型的嵌套查询参数，大于、小于、范围之间的值所有类型的查询？

任何执行此操作的 npm 模块、git hub 代码或代码片段？示例：对于我的 api，我支持 qs npm 模块支持的所有类型的查询参数，其中我的搜索 api 是从弹性云中获取的。

所以如果我得到查询

?title=Resurgence&causes=General&location.city=Mysuru&latitude=12.9803047&longitude=77.62949349999997&distance=50000&pageNumber=0&pageSize=10& organisation._id=5c36dd152edb5028fd7655a4

然后查询字符串将由 qs npm 模块转换为 json 对象，并给出如下的 json 对象

{"title":"Resurgence","causes":"General","location.city":"Mysuru","latitude":"12.9803047","longitude":"77.62949349999997","distance":"50000","pageNumber":"0","pageSize":"10","organisation._id":"5c36dd152edb5028fd7655a4"}

在弹性搜索中搜索时，我想将其转换为弹性搜索查询对象，如下所示。所以我只是在寻找一个 npm 模块，它将 qs 模块的查询字符串 json 转换为弹性云查询体？
