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