• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (hoc thieu)) sang - manh trung ((dap hang) OR (dat hang)) cong san toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (hoc thieu)) sang - manh trung ((dap hang) OR (dat hang)) cong san toan tap*".
