Perhaps you should try some spelling variations:
literatura author » literature author, literature authors, literatur autor
en letteratura » una letteratura, di letteratura, la letteratura
de literatura » de litterature, la literatura, y literatura
e letteratura » y literatura, e literatur
grande livre » grand livre, grands livres, grande liberte
i grande » di grande, i grunde, i grand
i gran » i grand, i grain, i grani

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 gran libro de literatura author ) OR ( i grande livre ((en letteratura) OR (e letteratura)) arte )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i gran libro de literatura author ) or ( i grande livre ((en letteratura) OR (e letteratura)) arte ))".
• Adding a wildcard symbol may retrieve word variants: (( i gran libro de literatura author ) or ( i grande livre ((en letteratura) OR (e letteratura)) arte ))*.
