I need an alternative to $nin in mongodb. As we know, we can achieve the "IN" query operation by performing "OR" query as well.

In the same way, how can I achieve "NOT IN" functionality in mongodb without using $nin ? What are the alternatives to using $nin in mongodb to acheive exactly same results ?

I found that there is a operator $nor which exactly does this function. It works as the negation of $or.",
