• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - manh ((trung va) OR (truong va)) dung huong ((dan toan) OR (dan than)) ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - manh ((trung va) or (truong va)) dung huong ((dan toan) OR (dan than)) ban*".
