• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) y ((nang mai) OR (nang ma)) hoi. lieu va cam luc gia thanh tai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) y ((nang mai) OR (nang ma)) hoi. lieu va cam luc gia thanh tai cua triet".
