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