Perhaps you should try some spelling variations:
"sociologist" » "sociological"
"sociologists" » "sociologicals", "sociological", "radiologists"
"sociologicals" » "sociological", "sociologicas", "sociologicos"
"sociologically" » "sociological", "psychologically", "biologically"

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