Perhaps you should try some spelling variations:
research progresses » research progress, research processes, research programmes
research projectses » research projektes, research project, research processes
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 progresses ) OR ( research projectses ))) OR ((( research process ) OR ( research projects )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( research progresses ) or ( research projectses ))) or ((( research process ) OR ( research projects ))))".
• Adding a wildcard symbol may retrieve word variants: (((( research progresses ) or ( research projectses ))) or ((( research process ) OR ( research projects ))))*.
