How can I do something like this: db.my_collection.find(‘myObj.myField’ : { $not : /abc/i });

How can I do something like this:

db.my_collection.find('myObj.myField' : { $not : /abc/i });

Which means to retrieve all the objects in which myField value does not contain abc substring (case-insensitive).

Thanks
