Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
della letteratura » nella letteratura, e letteratura
literatura en » literatura y
literatura de » literatura y
grunde libro » grunde fir, und libro
grunde gibt » grund gibt, grunde mit, grunde geht
libri del » libro del, libri de, libri duo
i grundei » i grunde, i grund

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 grundei libri del ((literatura de) OR (literatura en)) ) OR ( i ((((grunde libro) OR (grunde gibt))) OR (gran libro)) della letteratura sarda ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grundei libri del ((literatura de) or (literatura en)) ) or ( i ((((grunde libro) OR (grunde gibt))) or (gran libro)) della letteratura sarda ))*".
