• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ly quang ((cua hoi) OR (cau hoi)). hieu van nam xuc va thanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ly quang ((cua hoi) or (cau hoi)). hieu van nam xuc va thanh vi cua triet*".
