Perhaps you should try some spelling variations:
"research progression" » "research regression", "research progress", "research professional"
"research profession" » "research professional", "research professionals", "research progressions"
"research progresses" » "research progress", "research processes", "research programmes"

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 progresses")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"research profession\") or (((\"research progression\") OR (\"research progresses\"))))".
• Removing quotes may allow a broader search: (( research profession ) or ((( research progression ) OR ( research progresses )))).
• Adding a wildcard symbol may retrieve word variants: (("research profession") or ((("research progression") OR ("research progresses"))))*.
