Perhaps you should try some spelling variations:
research profession » research professional, research progression, research professionals
research prozess » research progress, research propels, research processes
research process » research progress, research projects, research problems

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: (((( research prozess ) OR ( research profession ))) OR ( research process ))*.
