Perhaps you should try some spelling variations:
"physical anthropology" » "medical anthropology", "philosophical anthropology"
"visual anthropology" » "cultural anthropology", "criminal anthropology", "medical anthropology"
"social anthropology" » "medical anthropology"

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: (("visual anthropology") OR ((("physical anthropology") OR ("social anthropology")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"visual anthropology\") or (((\"physical anthropology\") OR (\"social anthropology\"))))".
• Removing quotes may allow a broader search: (( visual anthropology ) or ((( physical anthropology ) OR ( social anthropology )))).
• Adding a wildcard symbol may retrieve word variants: (("visual anthropology") or ((("physical anthropology") OR ("social anthropology"))))*.
