Get documents with field that isn't a particular string

Question

I want to get the documents from MongoDB that don't have the field "name":"John" (just an example).

How can I do this?

For getting the documents that have the field "name":"John" I use:

db.col.find({"name":"John"})

I've already tried ...find(!{"name":"John"}).

Answer 1

db.col.find({"name":{$ne: "John"}})

should work, here are docs: Mongo, Advanced Queries.

Answer 2

Just use $ne selector like this:

db.col.find({"name":{$ne:"John"}})
