Perhaps you should try some spelling variations:
letteratura sulla » letteratura russa, letteratura del
e letteratura » y literatura, e literatur
literatura de » literatura y
literatura en » literatura y
grunde die » grunde der, grunde des, grundlage die
livre ii » livres ii, livre iii, livre i
die e » die _, die 7, die 5

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 grunde die e letteratura sulla ) OR ( i grand livre ii ((literatura de) OR (literatura en)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grunde die e letteratura sulla ) or ( i grand livre ii ((literatura de) OR (literatura en)) ))".
• Adding a wildcard symbol may retrieve word variants: (( i grunde die e letteratura sulla ) or ( i grand livre ii ((literatura de) OR (literatura en)) ))*.
