• If you are trying to use Boolean operators, they must be ALL CAPS: (( i gran libro de literature author ) OR ( i grani ((libero e) OR (liber de)) letteratura arti )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i gran libro de literature author ) or ( i grani ((libero e) OR (liber de)) letteratura arti ))".
• Adding a wildcard symbol may retrieve word variants: (( i gran libro de literature author ) or ( i grani ((libero e) OR (liber de)) letteratura arti ))*.
