• If you are trying to use Boolean operators, they must be ALL CAPS: ((((theo chieu) OR (theo chu))) OR (ho chieu)) sang - thanh trung cua truong cong tac toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((theo chieu) OR (theo chu))) or (ho chieu)) sang - thanh trung cua truong cong tac toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((((theo chieu) OR (theo chu))) or (ho chieu)) sang - thanh trung cua truong cong tac toan cau*.
