• If you are trying to use Boolean operators, they must be ALL CAPS: doc sach dao ((cong ha) OR (dong ha)) noi. hieu va cham xuc ((va dan) OR (dia danh)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc sach dao ((cong ha) OR (dong ha)) noi. hieu va cham xuc ((va dan) or (dia danh)) vi cua te".
