e letteratura » y literatura, e literatur
id favorite » his favorite, _ favorite, my favorite

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 gran) OR (i grain)) libro su letteratura arti ) OR ( ((i gran) OR (i grain))id favorite e letteratura e )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((i gran) OR (i grain)) libro su letteratura arti ) or ( ((i gran) OR (i grain))id favorite e letteratura e ))".
• Adding a wildcard symbol may retrieve word variants: (( ((i gran) OR (i grain)) libro su letteratura arti ) or ( ((i gran) OR (i grain))id favorite e letteratura e ))*.
