Perhaps you should try some spelling variations:
"epistemologia" » "epistemologie", "epistemologies", "epistemology"
"epistemologische" » "epidemiologische", "epistemologie", "epistemologies"
"epistemologists" » "epistemologies", "epidemiologists", "epistemologie"
"epistemological" » "epidemiological"

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