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