• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ty ((xang cau) OR (((bang cau) OR (bang cac)))) hoi. hieu va cao xuc va danh di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ty ((xang cau) or (((bang cau) OR (bang cac)))) hoi. hieu va cao xuc va danh di cua triet*".
