Notices

1. Name mapping

mongoose.model('User', userSchema);

The model User here is corresponding to the mongodb's collection name users.

You can specify the collection name: http://stackoverflow.com/questions/7486528/mongoose-force-collection-name

2. If no results return, find will return empty array, but findOne will return null
