Perhaps you should try some spelling variations:
"anthropology doing" » "anthropology using", "anthropology being", "anthropology locating"
"anthropology first" » "anthropology fast", "anthropology from", "anthropology film"
"anthropology dirk" » "anthropology film", "anthropology iii", "anthropology art"

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