Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
de letteratura » di letteratura, de litteratura, de litterature
x letteratura » _ letteratura, di letteratura, la letteratura
e letteratura » y literatura, e literatur
grandi libro » gran libro, grand livre, amandi libri
amanda ii » bamenda ii, amanda l, amanda j
e grandi » le grandi, de grandi, e grande

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: (( _ amanda ii ((x letteratura) OR (e letteratura)) fra ) OR ( e grandi libro de letteratura sarda ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( _ amanda ii ((x letteratura) OR (e letteratura)) fra ) or ( e grandi libro de letteratura sarda ))*".
