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