Hi @Prasad_Saya, Thanks for your response. But I am not expecting that. $exists will return if the key is present or not. What I want is I would like to get that any other exists than given key in object field or I want is if that object has multiple keys or not i.e size of object length should be greater than 1.
So, for that, we used $gt operator. So, is that the right thing to do, Any downside of doing as we want to leverage indexes as well?
