• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (su sach)) thu nang ((o hoi) OR (co hoi)). hieu va cham cuu ban danh d cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (su sach)) thu nang ((o hoi) OR (co hoi)). hieu va cham cuu ban danh d cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (su sach)) thu nang ((o hoi) OR (co hoi)). hieu va cham cuu ban danh d cua tre*.
