Perhaps you should try some spelling variations:
"anthropology chavin" » "anthropology can", "anthropology chris", "anthropology david"
"anthropology alain" » "anthropology spain", "anthropology aat", "anthropology alps"
"anthropology case" » "anthropology care", "anthropology based", "anthropology fast"

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: (("anthropology alain") OR ((("anthropology chavin") OR ("anthropology case")))).
• Removing quotes may allow a broader search: (( anthropology alain ) or ((( anthropology chavin ) or ( anthropology case )))).
• Adding a wildcard symbol may retrieve word variants: (("anthropology alain") or ((("anthropology chavin") or ("anthropology case"))))*.
