I mis-operate to update a piece of data, and then the data is not backed up, How can I find the data of the previous version?
Pretty certain you can't. But you don't even say what data you are talking about. ALWAYS have a backup /recovery plan in place.
My misoperation is like this, I should be querying with GET.

{}
Then no, it's been replaced with an empty document.
