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