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