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

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