• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((canh manh) OR (lanh manh)) cua nhung cong ((dan toan) OR (van than)) tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((canh manh) OR (lanh manh)) cua nhung cong ((dan toan) or (van than)) tap".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((canh manh) OR (lanh manh)) cua nhung cong ((dan toan) or (van than)) tap*.
