Perhaps you should try some spelling variations:
"research write paper" » "research white paper", "research written paper", "research site paper", "research white papers"
"research while paper" » "research where paper", "research which paper", "research what paper", "research white paper", "research while pair", "research while chapter"

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 write paper") OR ("research while paper"))*.
• Removing quotes may allow a broader search: (( research write paper ) or ( research while paper ))*.
