• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach y)) nang ((ma hoi) OR (xa hoi)). hieu qua cam tuc va tinh day cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach y)) nang ((ma hoi) or (xa hoi)). hieu qua cam tuc va tinh day cua triet".
