Perhaps you should try some spelling variations:
"philanthropists" » "philanthroposs", "philanthropys"
"philanthropist" » "philanthropos", "philanthropy"
"philanthropistsus" » "philanthropossus", "philanthropysus", "philanthropismus", "philanthropisches", "philanthropicus"
"philanthropism" » "philanthropinism", "philanthropismus", "philanthrophist"

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