Perhaps you should try some spelling variations:
a letteratura » la letteratura, _ letteratura, tra letteratura
e letteratura » y literatura, e literatur
grunde livre » grande livre, grand livre, grunde liegen
libro dell » libro della, libro delle, libro del
i grundei » i grund

You may be able to get more results by adjusting your search query.

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