• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien hach) OR (chinh sach)) - thanh trung cam nhung cong ((dan phan) OR (dan chan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien hach) or (chinh sach)) - thanh trung cam nhung cong ((dan phan) OR (dan chan)) cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((thien hach) or (chinh sach)) - thanh trung cam nhung cong ((dan phan) OR (dan chan)) cau*.
