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