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

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 (("sociologie" OR "sociologia") OR "sociology")).
• Removing quotes may allow a broader search: (( sociologist or radiologists ) or (( sociologie or sociologia ) or sociology )).
• Adding a wildcard symbol may retrieve word variants: (("sociologist" or "radiologists") or (("sociologie" or "sociologia") or "sociology"))*.
