• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu tinh) or (chieu sach)) - canh doanh cua tong ((thong tan) OR (thong than)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu tinh) or (chieu sach)) - canh doanh cua tong ((thong tan) OR (thong than)) toan ban*.
