Perhaps you should try some spelling variations:
research problemses » research problems, research problem, research progresses
research processes » research procedures, research progress, research practices
research process » research progress, research problems, research program

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 processes ) OR ((( research problemses ) OR ( research project ))))) OR ((( research process ) OR ( research projects )))).
• Adding a wildcard symbol may retrieve word variants: (((( research processes ) or ((( research problemses ) or ( research project ))))) or ((( research process ) or ( research projects ))))*.
