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