Perhaps you should try some spelling variations:
"research progression" » "research regression", "research progress", "research progresses"
"research professor" » "research profession", "research prozess", "search processor"
"research processes" » "research procedures", "research progress", "research practices", "research progresses", "research problemses", "research projectes"
"research projects" » "research project"
"research process" » "research progress", "research problems", "research project"

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