Perhaps you should try some spelling variations:
"philanthropismus" » "philanthropicus", "philanthropisches", "philanthropies", "philanthropinismus", "philanthrophistus", "philanthroposus"
"philanthropism" » "philanthropinism", "philanthrophist", "philanthropos"
"philanthropists" » "philanthroposs", "philanthropys"
"philanthropist" » "philanthropos", "philanthropy"

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