Perhaps you should try some spelling variations:
"philanthropists" » "philanthropic", "philanthropics", "philanthroposs", "philanthropys"
"philanthropinism" » "philanthropism", "philanthrophist", "philanthropicus"
"philanthropist" » "philanthropic", "philanthropos", "philanthropy"
"philanthropies" » "philanthropie", "philanthropic", "philanthropos"

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