• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc sieu) OR (hoc hien)) tinh - thanh ((trung cua) OR (truong quan)) ban cong van toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sieu) OR (hoc hien)) tinh - thanh ((trung cua) or (truong quan)) ban cong van toan cao".
• Adding a wildcard symbol may retrieve word variants: ((hoc sieu) OR (hoc hien)) tinh - thanh ((trung cua) or (truong quan)) ban cong van toan cao*.
