Perhaps you should try some spelling variations:
institutionen politischer » institutionen politische, institutions political, institutions politics
institution politischer » institutionen politische, institutions political, institutions politics
teoria de » teoria della
de idee » die idee, der idee, di idee
2 whole » _ whole
idee 2 » idee 3, idee _, idee 4

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "teoria de idee 2 whole ((institution politischer) OR (institutionen politischer))".
• Adding a wildcard symbol may retrieve word variants: teoria de idee 2 whole ((institution politischer) OR (institutionen politischer))*.
