Perhaps you should try some spelling variations:
della letteratura » nella letteratura, e letteratura
della literatura » pela literatura, nella letteratura, de literatura
la literatura » la litterature, a literature
literatura di » literatura de, literatura do, literatura i
grain piero » grain pro
l la » l l, l a, l le

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: (( _ amanda l la literatura di ) OR ( i ((grain piero) OR (gian piero)) ((della literatura) OR (della letteratura)) e ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( _ amanda l la literatura di ) or ( i ((grain piero) or (gian piero)) ((della literatura) OR (della letteratura)) e ))*".
