• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (vu bach)) ky tang ma hoi. thien van cam xuc van thanh ((hai cua) OR (dai cua)) su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (vu bach)) ky tang ma hoi. thien van cam xuc van thanh ((hai cua) OR (dai cua)) su".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (vu bach)) ky tang ma hoi. thien van cam xuc van thanh ((hai cua) OR (dai cua)) su*.
