Perhaps you should try some spelling variations:
"sociologist" » "sociological"
"sociologists" » "sociologicals", "sociological"
"radiologists" » "radiological"
"sociologie" » "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 "sociology") OR "sociologists"))*.
• Removing quotes may allow a broader search: ((( sociologist or radiologists ) or biologists ) or (( sociologie or sociology ) or sociologists ))*.
