Perhaps you should try some spelling variations:
distribuzioni politiche » istituzioni politiche, distribution political, costruzioni politiche
teoria della » storia della
storia del » historia del, storia della, storia e
die delle » die dell, die pelle, die modelle
die elle » die elbe, die elde, die ele

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: ((teoria della) OR (storia del)) idee ((die delle) OR (die elle)) distribuzioni politiche.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((teoria della) or (storia del)) idee ((die delle) OR (die elle)) distribuzioni politiche".
• Adding a wildcard symbol may retrieve word variants: ((teoria della) or (storia del)) idee ((die delle) OR (die elle)) distribuzioni politiche*.
