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 projects") OR ("research project"))))) OR ("research problemses"))) OR ("research process")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"research processes\") or (((\"research projects\") OR (\"research project\"))))) or (\"research problemses\"))) or (\"research process\"))".
• Removing quotes may allow a broader search: (((((( research processes ) or ((( research projects ) OR ( research project ))))) or ( research problemses ))) or ( research process )).
• Adding a wildcard symbol may retrieve word variants: (((((("research processes") or ((("research projects") OR ("research project"))))) or ("research problemses"))) or ("research process"))*.
