Perhaps you should try some spelling variations:
epistemologie » epistemology, epistemologische, epistemological
epistemologies » epistemologys, epistemologisches, epistemologicals, epistemological, epistemology
epistemologisches » epistemologische, epistemologischen, epistemologischer

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: ( epistemologie OR ((epistemologies OR epistemologisches) OR epidemiology) )*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "( epistemologie or ((epistemologies OR epistemologisches) or epidemiology) )*".
