• If you are trying to use Boolean operators, they must be ALL CAPS: ho chiet tach - thanh thang va nhung cong ((((san van) OR (luan van))) OR (san tay)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - thanh thang va nhung cong ((((san van) OR (luan van))) or (san tay)) cau*".
