Perhaps you should try some spelling variations:
"philanthropists" » "philanthroposs"
"philanthropist" » "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: (("philanthropists" OR ("philanthropist" OR "philanthropy")) OR ("philanthropic" OR "philanthropismus")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philanthropists\" or (\"philanthropist\" OR \"philanthropy\")) or (\"philanthropic\" or \"philanthropismus\"))".
• Removing quotes may allow a broader search: (( philanthropists or ( philanthropist OR philanthropy )) or ( philanthropic or philanthropismus )).
• Adding a wildcard symbol may retrieve word variants: (("philanthropists" or ("philanthropist" OR "philanthropy")) or ("philanthropic" or "philanthropismus"))*.
