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