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