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