Yii - addInCondition

first thing is i have these data in my db:

family_name      employee_rank
Dixon            1
Greene           1
Grimes           1
//and all other family_names with different employee_rank

i have a list of employees that i need to generate. i have this condition in my $criteria where i am not including employee_rank = 1 except family_name = 'Grimes'

$criteria->addNotInCondition('employee_rank', array('1'));

How can i include family_name = "Grimes" in the search condition. i tried using

$criteria->addInCondition('family_name', array('Grimes'));

but this will only result to searching only Grimes and not include everyone else. I also tried using this

$criteria->addNotInCondition('employee_rank', array('9', '1'));
$criteria->addNotInCondition('family_name', array('Dixon', 'Greene'));

This is the correct thing that i want but i need a condition where i dont need to use $criteria->addNotInCondition('family_name', array('Dixon', 'Greene')); but a condition where family_name = "Grimes".

According to documentation methods addNotInCondition and addInCondition has third argument $operator.

$criteria->addNotInCondition('employee_rank', array('9', '1'), 'OR');
$criteria->compare('family_name', 'Grimes', false, 'OR');
