• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach y)) nang ((cao hoi) OR (cau hoi)). thien van tham tuc va hanh lai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sach y)) nang ((cao hoi) OR (cau hoi)). thien van tham tuc va hanh lai cua triet*".
