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