Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
iii literature » iii literatur, viii literatur, ii literatur
7 letteratura » e letteratura, _ letteratura, di letteratura
ii literature » ii literatur, i literature, vii literatur
grunde die » grunde der, grunde des, grundlage die
die 7 » die _

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 7 letteratura sarda ) OR ( i grand livre ((iii literature) OR (ii literature)) de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grunde die 7 letteratura sarda ) or ( i grand livre ((iii literature) OR (ii literature)) de ))".
• Adding a wildcard symbol may retrieve word variants: (( i grunde die 7 letteratura sarda ) or ( i grand livre ((iii literature) OR (ii literature)) de ))*.
