Perhaps you should try some spelling variations:
"research procedures" » "search procedure", "research proceedings", "research process"
"research processes" » "research process", "research projects", "research progress"
"search procedures" » "search process"

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 procedures") OR ("research processes"))) OR ("search procedures")).
• Removing quotes may allow a broader search: (((( research procedures ) or ( research processes ))) or ( search procedures )).
• Adding a wildcard symbol may retrieve word variants: (((("research procedures") or ("research processes"))) or ("search procedures"))*.
