• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) y nang cai hoa. hieu ve cham luc ((va hanh) OR (va danh)) hai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) y nang cai hoa. hieu ve cham luc ((va hanh) or (va danh)) hai cua triet*".
