• If you are trying to use Boolean operators, they must be ALL CAPS: (( i gran libro la litterature author ) OR ( i grandi ((liberali du) OR (liberali et)) letteratura arte ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i gran libro la litterature author ) or ( i grandi ((liberali du) OR (liberali et)) letteratura arte ))*".
