Perhaps you should try some spelling variations:
letteratura arte » letteratura arti, letteratura sarda, letteratura e
e letteratura » y literatura, e literatur
literature de » litterature de, literature die, literature d
i literature » ii literature
grunde des » grunde der, grundzuge des, grundlage des
grund des » grund der, grundung des
i grand » i grunde
livre i » livro i, livre 1, livre qui

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 ((grunde des) OR (grund des)) e letteratura arte ) OR ( i grand livre i literature de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i ((grunde des) OR (grund des)) e letteratura arte ) or ( i grand livre i literature de ))".
• Adding a wildcard symbol may retrieve word variants: (( i ((grunde des) OR (grund des)) e letteratura arte ) or ( i grand livre i literature de ))*.
