Perhaps you should try some spelling variations:
"biographer" » "biographien", "biography", "geographer"
"biographie" » "biography", "biographical"
"biographiessn" » "biographyssn", "biographicalssn", "biographien", "biographierten", "biographisch", "biographicalsn"
"biographies" » "biographys", "biographicals", "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 "biographie") OR ("biographiessn" OR "biographies")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"biographer\" or \"biographie\") or (\"biographiessn\" OR \"biographies\"))".
• Removing quotes may allow a broader search: (( biographer or biographie ) or ( biographiessn OR biographies )).
• Adding a wildcard symbol may retrieve word variants: (("biographer" or "biographie") or ("biographiessn" OR "biographies"))*.
