• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (hoc sach)) ((thi hanh) OR (thi thanh)) xu hoi. hieu ve cam luc va danh tri cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (hoc sach)) ((thi hanh) OR (thi thanh)) xu hoi. hieu ve cam luc va danh tri cua triet".
