• If you are trying to use Boolean operators, they must be ALL CAPS: cho chieu sach - ((anh tang) OR (anh bang)) cua hoang ((phuong dan) OR (phuong doan)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho chieu sach - ((anh tang) or (anh bang)) cua hoang ((phuong dan) OR (phuong doan)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: cho chieu sach - ((anh tang) or (anh bang)) cua hoang ((phuong dan) OR (phuong doan)) toan cao*.
