Perhaps you should try some spelling variations:
letteratura da » letteratura di, letteratura del, letteratura fra
grunde livre » grande livre, grand livre, grunde liegen
libri della » libri dalla, libri nella, libri del
libro della » libro del, piero della
i grund » i grunde, i ground
i grand » i grunde

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) OR (i grand)) ((libri della) OR (libro della)) letteratura da ) OR ( i ((grunde livre) OR (grunde gegen)) _ letteratura e )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((i grund) OR (i grand)) ((libri della) or (libro della)) letteratura da ) or ( i ((grunde livre) or (grunde gegen)) _ letteratura e ))".
• Adding a wildcard symbol may retrieve word variants: (( ((i grund) OR (i grand)) ((libri della) or (libro della)) letteratura da ) or ( i ((grunde livre) or (grunde gegen)) _ letteratura e ))*.
