• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky sang tao hoi. hieu he nam thu xa danh sai ((cua triet) OR (((su triet) OR (su viet)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky sang tao hoi. hieu he nam thu xa danh sai ((cua triet) or (((su triet) OR (su viet))))".
