Perhaps you should try some spelling variations:
distribuzione politiche » istituzioni politiche, distributive politics, costruzioni politiche
distribution political » distribution policy, distributions statistical
storia der » storia del, storia dei, historia der
storia de » storia del, storia dei, storia e
idee e » idee de, idee 3, idee _

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 der) OR (storia de)) idee e della ((distribuzione politiche) OR (distribution political)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((storia der) or (storia de)) idee e della ((distribuzione politiche) OR (distribution political))".
• Adding a wildcard symbol may retrieve word variants: ((storia der) or (storia de)) idee e della ((distribuzione politiche) OR (distribution political))*.
