• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cac)) ky nang ho hoi. hieu ve cham tuc ((van hanh) OR (van thanh)) di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su cac)) ky nang ho hoi. hieu ve cham tuc ((van hanh) or (van thanh)) di cua triet*".
