Perhaps you should try some spelling variations:
"research problemses" » "research problems", "research problem", "research progresses"
"research processes" » "research process", "research procedures", "research practices"
"research progress" » "research program", "research problems", "research project"
"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 processes") OR ("research problemses"))) OR ((("research progress") OR ("research projects")))).
• Removing quotes may allow a broader search: (((( research processes ) or ( research problemses ))) or ((( research progress ) or ( research projects )))).
• Adding a wildcard symbol may retrieve word variants: (((("research processes") or ("research problemses"))) or ((("research progress") or ("research projects"))))*.
