Perhaps you should try some spelling variations:
delete istituzioni » delle istituzioni, nelle istituzioni, le istituzioni
storia delle » storia della, teoria delle
teoria della » storia della
storia del » historia del, storia della, storia e
3 delete » _ delete, a delete, 9 delete

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: "((((storia delle) OR (teoria della))) OR (storia del)) idee 3 delete istituzioni (politiche" or politische").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((storia delle) OR (teoria della))) or (storia del)) idee 3 delete istituzioni (politiche\" or politische\")".
• Removing quotes may allow a broader search: ((((storia delle) OR (teoria della))) or (storia del)) idee 3 delete istituzioni (politiche or politische ).
• Adding a wildcard symbol may retrieve word variants: "((((storia delle) OR (teoria della))) or (storia del)) idee 3 delete istituzioni (politiche" or politische")*.
