Perhaps you should try some spelling variations:
"research progress" » "research program", "research projects"
"research prozess" » "research propels", "research processes", "research proteases"
"research process" » "research projects", "research problems", "research program"

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 process") OR ("research project"))) OR ("research progress"))))*.
• Removing quotes may allow a broader search: (( research prozess ) or ((((( research process ) or ( research project ))) or ( research progress ))))*.
