Perhaps you should try some spelling variations:
"philanthropinism" » "philanthropies", "philanthrophist", "philanthropicus"
"philanthropism" » "philanthropismus", "philanthrophist", "philanthropie"
"philanthropus" » "philanthropies", "philanthropie"

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