Perhaps you should try some spelling variations:
"economico antropologicas" » "economico metodologia", "economicao antropologicas", "economiao antropologicas", "economicaso antropologicas"
"historico antropologicos" » "estudio antropologico", "estudios antropologicos"
"economic anthropologist" » "economica anthropologist", "economia anthropologist", "economicas anthropologist"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"economic anthropologist\") OR (((\"economico antropologicas\") OR (\"historico antropologicos\"))))~".
• Removing quotes may allow a broader search: (( economic anthropologist ) OR ((( economico antropologicas ) OR ( historico antropologicos ))))~.
• Adding a wildcard symbol may retrieve word variants: (("economic anthropologist") OR ((("economico antropologicas") OR ("historico antropologicos"))))*.
