Perhaps you should try some spelling variations:
della letteratura » nella letteratura
duo letteratura » di letteratura, su letteratura, sua letteratura
e letteratura » y literatura, e literatur
magne libro » magni libri
i grund » i grunde, i ground, i grand
_ magne » _ magnet, _ magna, _ magneto

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 libri duo letteratura e ) OR ( _ magne libro ((della letteratura) OR (e letteratura)) sarda ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grund libri duo letteratura e ) or ( _ magne libro ((della letteratura) OR (e letteratura)) sarda ))*".
