Perhaps you should try some spelling variations:
"epistemologist" » "epistemologists", "epistemologies", "epistemologie"
"epistemologische" » "epistemological", "epistemologie", "epistemologies"
"epidemiologische" » "epidemiological", "epidemiologie", "epidemiologic"

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: ("epistemologist" OR ("epistemologische" OR "epidemiologische")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"epistemologist\" or (\"epistemologische\" OR \"epidemiologische\"))".
• Removing quotes may allow a broader search: ( epistemologist or ( epistemologische OR epidemiologische )).
• Adding a wildcard symbol may retrieve word variants: ("epistemologist" or ("epistemologische" OR "epidemiologische"))*.
