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