• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky nang x hoi. hieu ve chao xu ((va tinh) OR (van dich)) va cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) ky nang x hoi. hieu ve chao xu ((va tinh) or (van dich)) va cua triet*".
