• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - tran cong cua nhung cong van ((thanh cau) or (((nhanh cau) OR (nhanh cay))))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - tran cong cua nhung cong van ((thanh cau) or (((nhanh cau) OR (nhanh cay))))*.
