Perhaps you should try some spelling variations:
"research progression" » "research regression", "research progress", "research progresses"
"research profession" » "research professional", "research professionals", "research progressions"
"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 profession") OR ("research progression"))) OR ("research process")).
• Removing quotes may allow a broader search: (((( research profession ) or ( research progression ))) or ( research process )).
• Adding a wildcard symbol may retrieve word variants: (((("research profession") or ("research progression"))) or ("research process"))*.
