Perhaps you should try some spelling variations:
"universitaten di pisa" » "universitaten die pisa", "universitaten i pisa", "universitaten ii pisa"
"universitaten di pieta" » "universitaten die pieta", "universitaten i pieta", "universitaten ii pieta", "universitaten di pietro"
"universitaten de pieta" » "universitaten der pieta", "universitaten die pieta", "universitaten des pieta", "universitaten de piete", "universitaten de poeta", "universitaten de pietate"

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: (("universitaten di pisa") OR ((("universitaten di pieta") OR ("universitaten de pieta")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"universitaten di pisa\") or (((\"universitaten di pieta\") OR (\"universitaten de pieta\"))))".
• Removing quotes may allow a broader search: (( universitaten di pisa ) or ((( universitaten di pieta ) OR ( universitaten de pieta )))).
• Adding a wildcard symbol may retrieve word variants: (("universitaten di pisa") or ((("universitaten di pieta") OR ("universitaten de pieta"))))*.
