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