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