Perhaps you should try some spelling variations:
"sociologist" » "sociological"
"sociologists" » "sociologicals", "sociological"
"radiologists" » "radiological"
"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 "radiologists") OR "biologists") OR ((("sociologie" OR "sociologists") OR "sociology") OR "sociologia"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"sociologist\" or \"radiologists\") or \"biologists\") or (((\"sociologie\" OR \"sociologists\") or \"sociology\") or \"sociologia\"))*".
• Removing quotes may allow a broader search: ((( sociologist or radiologists ) or biologists ) or ((( sociologie OR sociologists ) or sociology ) or sociologia ))*.
