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