Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
letteratura del » letteratura e, letteratura di, literatura del
de letteratura » e letteratura, di letteratura, de litteratura
grund libro » gran libro, und libro
die land » die lander, die lange
i grund » i ground, i grand
die lan » die lange, die langs

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 grund libro de letteratura del ) OR ( i grunde ((die lan) OR (die land)) letteratura sarda ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grund libro de letteratura del ) or ( i grunde ((die lan) OR (die land)) letteratura sarda ))*".
