• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang x hoi. hieu ((ve cam) OR (ve cham)) duc va thanh ve va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky nang x hoi. hieu ((ve cam) OR (ve cham)) duc va thanh ve va triet*".
