Perhaps you should try some spelling variations:
della letteratura » nella letteratura, e letteratura
letteratura di » literatura de
inbound links » outbound links
grounde livre » grande livre, grand livre
ground links » und links
i grounde » i grunde, i ground, i grounds

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 links) OR (inbound links)) della letteratura di ) OR ( i grounde livre _ letteratura e )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i ((ground links) OR (inbound links)) della letteratura di ) or ( i grounde livre _ letteratura e ))".
• Adding a wildcard symbol may retrieve word variants: (( i ((ground links) OR (inbound links)) della letteratura di ) or ( i grounde livre _ letteratura e ))*.
