Perhaps you should try some spelling variations:
della letteratura » nella letteratura, e letteratura
della literatura » pela literatura, nella letteratura, la literatura
literatura di » literatura de, literatura do, literatura i
grain piero » gian piero, grain pro
i grain » ii grain
j la » a la, _ la, j a
y la » a la

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