Find documents with arrays not containing a document with a particular field value in MongoDB

Question

I\'m trying to find all documents that do not contain at least one document with a specific field value. For example here is a sample collection:

{  _id : 1         


        

Answer 1

Using $nin will work, but you have the syntax wrong. It should be:

db.collection.find({'docs.foo': {$nin: [1]}})
