• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu bach)) ((tay lang) OR (tay quang)) van hoi. hieu ve chat thuc va dinh va cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu bach)) ((tay lang) OR (tay quang)) van hoi. hieu ve chat thuc va dinh va cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (vu bach)) ((tay lang) OR (tay quang)) van hoi. hieu ve chat thuc va dinh va cua tre*.
