Perhaps you should try some spelling variations:
"philanthrophist" » "philanthropist", "philantropist", "philanthropos"
"philanthropists" » "philanthropos"
"philanthropism" » "philanthropist", "philanthropinism", "philanthropismus"

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