• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) y sang ((ma hoi) OR (xa hoi)). lieu van tham hoc va danh di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) y sang ((ma hoi) or (xa hoi)). lieu van tham hoc va danh di cua triet".
