Perhaps you should try some spelling variations:
"philanthropies" » "philanthropie", "philanthropos", "philanthropist"
"philanthropists" » "philanthropos"
"philanthropismus" » "philanthropicus", "philanthropism", "philanthropisches"

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