Perhaps you should try some spelling variations:
research progresses » research progression, research programmes, research congresses
research processes » research process, research procedures, research projects
research progress » research program, research project, research projects

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