Perhaps you should try some spelling variations:
costruzioni politiche » istituzioni politiche, condizioni politiche, considerazioni politiche
historia del » historia de
die sende » die spende, die sender, die sekunde
die ende » die enden, die end, die endo

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