Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
literatur greca » literatura graeca, literatura grega, literaturas grecia
libro e » libro de, libero e, libro i
die lan » die land, die lange, die langs
die la » die lage, die land, die lamb
i und » _ und, 2 und
1 und » _ und

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 und) OR (1 und)) libro e literatur greca ) OR ( i grunde ((die la) OR (die lan)) letteratura sarda )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((i und) or (1 und)) libro e literatur greca ) or ( i grunde ((die la) OR (die lan)) letteratura sarda ))".
• Adding a wildcard symbol may retrieve word variants: (( ((i und) or (1 und)) libro e literatur greca ) or ( i grunde ((die la) OR (die lan)) letteratura sarda ))*.
