Perhaps you should try some spelling variations:
"epistemologie" » "epistemologies", "epistemology", "epistemological"
"epistemologische" » "epistemological", "epidemiologische", "epistemologies"
"epistemologys" » "epistemology", "epistemologies", "epistemologias"

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 "epistemologische") OR "epistemologys").
• Removing quotes may allow a broader search: (( epistemologie or epistemologische ) or epistemologys ).
• Adding a wildcard symbol may retrieve word variants: (("epistemologie" or "epistemologische") or "epistemologys")*.
