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