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