Perhaps you should try some spelling variations:
"sociologist" » "sociological"
"sociologists" » "sociologicals", "sociological", "radiologists"
"sociologie" » "sociological"
"sociologia" » "sociological"

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: ((("sociologist" OR "sociologists") OR "biologists") OR ("sociologie" OR ("sociologia" OR "sociology")))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"sociologist\" or \"sociologists\") or \"biologists\") or (\"sociologie\" or (\"sociologia\" OR \"sociology\")))*".
• Removing quotes may allow a broader search: ((( sociologist or sociologists ) or biologists ) or ( sociologie or ( sociologia OR sociology )))*.
