• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (vu bach)) ky tang ma hoi. ((thien van) OR (thi van)) cam xuc van thanh hai 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) OR (thi van)) cam xuc van thanh hai cua su".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (vu bach)) ky tang ma hoi. ((thien van) OR (thi van)) cam xuc van thanh hai cua su*.
