Perhaps you should try some spelling variations:
literatur sarda » letteratura sarda, literatur sarcoma, literatur smarte
la litterature » a literature
la literatura » a literature
i grundei » i grunde, i grund
libro e » libro de, libero e, libro i
i grand » i grunde

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 libro e literatur sarda ) OR ( i grand bien ((la literatura) OR (la litterature)) e )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grundei libro e literatur sarda ) or ( i grand bien ((la literatura) OR (la litterature)) e ))".
• Adding a wildcard symbol may retrieve word variants: (( i grundei libro e literatur sarda ) or ( i grand bien ((la literatura) OR (la litterature)) e ))*.
