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