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

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