Perhaps you should try some spelling variations:
epistemologie » epistemologies, epistemology, epistemological
epistemologys » epistemology, epistemologies, epistemologias
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 ((epistemologys OR epistemologisches) OR epidemiology) )*.
