Perhaps you should try some spelling variations:
"philanthropist" » "philanthropos", "philanthropy"
"philanthropists" » "philanthroposs", "philanthropys"
"philanthropism" » "philanthropinism", "philanthropismus", "philanthrophist"
"philanthroposs" » "philanthropos", "philanthropies", "philanthropus"

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