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

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 ("philanthropies" OR "philanthropie")) OR "philanthropism").
• Removing quotes may allow a broader search: (( philanthropists or ( philanthropies or philanthropie )) or philanthropism ).
• Adding a wildcard symbol may retrieve word variants: (("philanthropists" or ("philanthropies" or "philanthropie")) or "philanthropism")*.
