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