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