MongoDB $ ne Explanation

Question

So, when I came across something like

db.papers.update({"authors cited" : {"$ne" : "Richie"}},
... {$push : {"authors cited" : "Richie"}})

I have no choice but to become completely embarrassed. Can someone explain this to me?

This will add Richie to the list of authors cited for an article that does not yet have Richie as the author.

An alternative would be to use $addToSet.

, , {{ : { "$ ne": "Richie" }} , " ", , " "?

. ( , , ), . Mongo "multikeys" .
