• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sach - thanh trung ((quan nhung) OR (cua nhung)) cong ((dan than) OR (ban than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sach - thanh trung ((quan nhung) OR (cua nhung)) cong ((dan than) or (ban than)) cau*".
