Perhaps you should try some spelling variations:
"research processes" » "research procedures", "research projects", "research progress", "research progresses", "research projectses", "research problemses"
"research process" » "research progress", "research projects", "research problems"
"research prozess" » "research progress", "research propels", "research proteases"

You may be able to get more results by adjusting your search query.

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