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