Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
de letteratura » e letteratura, di letteratura, de litteratura
ii literatur » vi literatur, viii literatur
i literatur » vi literatur, i literature, vii literatur
iv gran » iv grand, iv grain, iv gram
i grani » i grandi, i grand, dei 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: (( iv gran libro ((i literatur) OR (ii literatur)) a1 ) OR ( i grani libro de letteratura sarda )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( iv gran libro ((i literatur) OR (ii literatur)) a1 ) or ( i grani libro de letteratura sarda ))".
• Adding a wildcard symbol may retrieve word variants: (( iv gran libro ((i literatur) OR (ii literatur)) a1 ) or ( i grani libro de letteratura sarda ))*.
