FBFriendModel.find({ id:333 },function(err,docs){
    docs.remove();  //Remove all the documents that match!

The above mentioned does not appear to operate. The records remain. Can someone fix? Thanks.

docs is a range of documents. therefore it does not possess a mongooseModel.remove() -method.

You are able to iterate and take away each document within the array individually.

Or - because it appears like you're locating the documents with a (most likely) unique id - use findOne rather than find.
