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

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 ("sociologicals" OR "sociologicas"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"sociologist\" or (\"radiologists\" or (\"sociologicals\" OR \"sociologicas\")))".
• Removing quotes may allow a broader search: ( sociologist or ( radiologists or ( sociologicals OR sociologicas ))).
• Adding a wildcard symbol may retrieve word variants: ("sociologist" or ("radiologists" or ("sociologicals" OR "sociologicas")))*.
