Perhaps you should try some spelling variations:
"sociologist" » "sociologists", "sociological"
"sociologicals" » "sociological", "sociologicas", "sociologically"
"radiologists" » "biologists", "radiological"
"sociologia" » "sociological", "sociology", "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 ("sociologicals" OR "radiologists")) OR "sociologia").
• Removing quotes may allow a broader search: (( sociologist or ( sociologicals or radiologists )) or sociologia ).
• Adding a wildcard symbol may retrieve word variants: (("sociologist" or ("sociologicals" or "radiologists")) or "sociologia")*.
