Perhaps you should try some spelling variations:
letteratura greca » literatura graeca, letteratura fra, literatura grega
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
i grounde » i grunde, i grounds, _ grounde
i ground » i group, i groups, i grunde
die land » die lander, die lange
link e » link a, link 2, link 4
die la » die lan, die lage, die lamb

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 ground ((link e) OR (link _)) letteratura greca ) OR ( i grounde ((die la) OR (die land)) letteratura sarda )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i ground ((link e) or (link _)) letteratura greca ) or ( i grounde ((die la) OR (die land)) letteratura sarda ))".
• Adding a wildcard symbol may retrieve word variants: (( i ground ((link e) or (link _)) letteratura greca ) or ( i grounde ((die la) OR (die land)) letteratura sarda ))*.
