• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky ((nang xa) OR (nang ma)) hoi. hieu ve cam tuc van hanh lai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ky ((nang xa) OR (nang ma)) hoi. hieu ve cam tuc van hanh lai cua triet*".
