Perhaps you should try some spelling variations:
"research procedures" » "search procedures", "search procedure", "research processes"
"research practices" » "research practice", "research perspectives"
"research projects" » "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 practices") OR ("research procedures"))) OR ("research projects")).
• Removing quotes may allow a broader search: (((( research practices ) or ( research procedures ))) or ( research projects )).
• Adding a wildcard symbol may retrieve word variants: (((("research practices") or ("research procedures"))) or ("research projects"))*.
