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