• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien danh) or (hieu manh)) - anh nang luan doanh truong ((van tuan) OR (van ban)) ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien danh) or (hieu manh)) - anh nang luan doanh truong ((van tuan) OR (van ban)) ban*.
