• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) or (hoi hieu)) lang - thanh trung cua thong cong ((sang than) OR (sang tao)) cap~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) or (hoi hieu)) lang - thanh trung cua thong cong ((sang than) OR (sang tao)) cap*.
