The $pullAll operator removes multiple values from an existing array. $pullAll provides the inverse operation of the $pushAll operator. Consider the following example:
db.collection.update( { field: value }, { $pullAll: { field1: [ value1, value2, value3 ] } } );
Here, $pullAll removes [ value1, value2, value3 ] from the array in field1, in the document that matches the query statement { field: value } in collection.
