Perhaps you should try some spelling variations:
"biographer" » "biographies", "biography", "geographer"
"biographien" » "biographies", "biographical", "biographiesn", "biographyn", "biographicaln"
"biographicaln" » "biographical", "biographically", "biographica"
"biographie" » "biographies", "biography", "biographical"

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