• If you are trying to use Boolean operators, they must be ALL CAPS: (( i amandi libri e ((letteratura del) OR (literatura del)) ) OR ( i grunde der della letteratura e )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i amandi libri e ((letteratura del) OR (literatura del)) ) or ( i grunde der della letteratura e ))".
• Adding a wildcard symbol may retrieve word variants: (( i amandi libri e ((letteratura del) OR (literatura del)) ) or ( i grunde der della letteratura e ))*.
