Perhaps you should try some spelling variations:
"research procedures" » "search procedures", "search procedure", "research processes"
"research problems" » "research progress", "research process", "research project"
"research program" » "research project"

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 problems") OR ("research program")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"research procedures\") or (((\"research problems\") OR (\"research program\"))))".
• Removing quotes may allow a broader search: (( research procedures ) or ((( research problems ) OR ( research program )))).
• Adding a wildcard symbol may retrieve word variants: (("research procedures") or ((("research problems") OR ("research program"))))*.
