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