• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ty xang xa hoi. hieu ((va tham) OR (va cham)) duc va hanh diem cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ty xang xa hoi. hieu ((va tham) OR (va cham)) duc va hanh diem cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) ty xang xa hoi. hieu ((va tham) OR (va cham)) duc va hanh diem cua tre*.
