Perhaps you should try some spelling variations:
"research procedures" » "search procedures", "research processes", "research proceedings", "search proceduress", "research processs", "research processess", "research proceduress"
"research procedure" » "search procedures", "research process", "research processes", "research procedures"
"search procedure" » "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 procedure"))) OR ("search procedure")).
• Removing quotes may allow a broader search: (((( research procedures ) or ( research procedure ))) or ( search procedure )).
• Adding a wildcard symbol may retrieve word variants: (((("research procedures") or ("research procedure"))) or ("search procedure"))*.
