Perhaps you should try some spelling variations:
sociologist » sociological
sociologists » sociologicals, sociological, biologists
radiologists » biologists, radiological
sociologie » sociologia, sociological
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 radiologists ) OR ( (sociologie OR (sociologists OR sociologicals)) OR sociology )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( sociologist or radiologists ) or ( (sociologie or (sociologists OR sociologicals)) or sociology ))".
• Adding a wildcard symbol may retrieve word variants: (( sociologist or radiologists ) or ( (sociologie or (sociologists OR sociologicals)) or sociology ))*.
