"OR" condition in filtermanager of Kibana plugin in a dashboard

Is there a way i can give "OR" condition in filtermanager while developing plugins.
As of now i am able to give the below statement which is applying AND condition for all the values and so i am getting no results found in the dashboard.
filterManager.add('directions',['east','west','north','south'], null,'my_directions_index');
Please let me know if i need to change the statement so that i can apply OR condition using filtermanager. Thanks

Please don't cross post, see Or condition in filtermanager of Kibana plugin
