• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y tang van hoi. hieu ((va cham) OR (va tham)) cuu ((ca danh) OR (ca dan)) dau cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y tang van hoi. hieu ((va cham) OR (va tham)) cuu ((ca danh) or (ca dan)) dau cua triet".
