Perhaps you should try some spelling variations:
"philanthropists" » "philanthropic", "philanthropos", "philanthropics", "philanthroposs"
"philanthropist" » "philanthropic", "philanthropos"
"philanthropy" » "philanthropic"

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