Perhaps you should try some spelling variations:
"research profession" » "research professional", "research progression", "research professionals"
"research problems" » "research progress", "research project", "research program"
"research process" » "research progress", "research projects", "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 process") OR ("research problems"))) OR ("research profession")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"research process\") OR (\"research problems\"))) or (\"research profession\"))".
• Removing quotes may allow a broader search: (((( research process ) OR ( research problems ))) or ( research profession )).
• Adding a wildcard symbol may retrieve word variants: (((("research process") OR ("research problems"))) or ("research profession"))*.
