• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) tinh - canh trinh quang ((nhung duong) OR (nhung dung)) xanh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) tinh - canh trinh quang ((nhung duong) OR (nhung dung)) xanh toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) tinh - canh trinh quang ((nhung duong) OR (nhung dung)) xanh toan cao*.
