Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
iii literature » ii literature, viii literatur, ii literatur
5 letteratura » e letteratura, _ letteratura, di letteratura
iii literatur » viii literatur, ii literatur, vii literatur
grunde der » grund der, grundzuge der, grundlage der
der 5 » der _, der 2, der 1

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 der 5 letteratura sarda ) OR ( i grand livre ((iii literature) OR (iii literatur)) de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grunde der 5 letteratura sarda ) or ( i grand livre ((iii literature) OR (iii literatur)) de ))".
• Adding a wildcard symbol may retrieve word variants: (( i grunde der 5 letteratura sarda ) or ( i grand livre ((iii literature) OR (iii literatur)) de ))*.
