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