• If you are trying to use Boolean operators, they must be ALL CAPS: theo tieu sach - thanh ((((tung cua) OR (dung cua))) OR (trung cua)) nhung cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - thanh ((((tung cua) OR (dung cua))) or (trung cua)) nhung cong dan than cau".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - thanh ((((tung cua) OR (dung cua))) or (trung cua)) nhung cong dan than cau*.
