Perhaps you should try some spelling variations:
x letteratura » e letteratura, di letteratura, la letteratura
_ letteratura » e letteratura, di letteratura, la letteratura
literatura de » literatura y, literatura en
e literatura » de literatura, y literatura, e literatur
grand libro » gran libro, grand livre
i grundei » i grunde, i grund
i grand » i grunde
libro e » libro de, libero e, libro i

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 ((x letteratura) OR (_ letteratura)) di ) OR ( i grand libro e literatura de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grundei libri ((x letteratura) OR (_ letteratura)) di ) or ( i grand libro e literatura de ))".
• Adding a wildcard symbol may retrieve word variants: (( i grundei libri ((x letteratura) OR (_ letteratura)) di ) or ( i grand libro e literatura de ))*.
