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