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