• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cac)) ky nang x ho. hieu ve ((nhan thuc) OR (nhan luc)) van nhanh li ca viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su cac)) ky nang x ho. hieu ve ((nhan thuc) OR (nhan luc)) van nhanh li ca viet*".
