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
de delle » de delley, de derde, de degre
de dolle » de double, de douze, de dol
de del » de deo

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