Perhaps you should try some spelling variations:
costruzioni politiche » istituzioni politiche, condizioni politiche, considerazioni politiche
teoria della » storia della
die delle » die dell, die pelle, die modelle
die elde » die elbe, die eldo, 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 e)) idee ((((die delle) OR (die zelle))) OR (die elde)) costruzioni politiche.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((teoria della) or (storia e)) idee ((((die delle) OR (die zelle))) or (die elde)) costruzioni politiche".
• Adding a wildcard symbol may retrieve word variants: ((teoria della) or (storia e)) idee ((((die delle) OR (die zelle))) or (die elde)) costruzioni politiche*.
