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

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