Perhaps you should try some spelling variations:
institutionen politische » institutionen politischer, institutions politics, institutional politics
institution politischer » institutionen politischer, institutions politics, institutions politiques
teoria delle » teoria della, storia della, teoria de
delle idee » delle aree
3 whole » _ whole, 2 whole

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 delle idee 3 whole ((institution politischer) OR (((institutionen politische) OR (institutions political)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "teoria delle idee 3 whole ((institution politischer) or (((institutionen politische) OR (institutions political))))".
• Adding a wildcard symbol may retrieve word variants: teoria delle idee 3 whole ((institution politischer) or (((institutionen politische) OR (institutions political))))*.
