• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (ho chieu)) tinh - nhanh tinh quang nhung ((tuong manh) OR (duong manh)) toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (ho chieu)) tinh - nhanh tinh quang nhung ((tuong manh) or (duong manh)) toan tap*".
