• If you are trying to use Boolean operators, they must be ALL CAPS: (( i gran libro ((de literature) OR (de literatura)) author ) OR ( i glareani liber de letteratura arte )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i gran libro ((de literature) OR (de literatura)) author ) or ( i glareani liber de letteratura arte ))".
