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