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