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