Perhaps you should try some spelling variations:
"philanthropies" » "philanthropie", "philanthropos", "philanthropist"
"philanthropism" » "philanthropist", "philanthropinism", "philanthropismus"
"philanthropists" » "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: (("philanthropies" OR "philanthropic") OR ("philanthropism" OR "philanthropists")).
• Removing quotes may allow a broader search: (( philanthropies or philanthropic ) or ( philanthropism or philanthropists )).
• Adding a wildcard symbol may retrieve word variants: (("philanthropies" or "philanthropic") or ("philanthropism" or "philanthropists"))*.
