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

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 ("sociologists" OR "sociologicals")) OR "biologists") OR "sociologie")*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"sociologist\" or (\"sociologists\" OR \"sociologicals\")) or \"biologists\") or \"sociologie\")*".
• Removing quotes may allow a broader search: ((( sociologist or ( sociologists OR sociologicals )) or biologists ) or sociologie )*.
