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"

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