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