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