Perhaps you should try some spelling variations:
"research scope paper" » "research school paper", "research second paper", "research science paper", "research sope paper", "research scoping paper", "research scopus papers"
"research write papers" » "research white papers", "research written papers", "research waste papers", "research white paper"
"research site paper" » "research sites paper", "research say paper", "research science paper", "research size paper", "research white paper", "research state paper"

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 site paper") OR ("research scope paper"))) OR ("research write papers"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"research site paper\") OR (\"research scope paper\"))) or (\"research write papers\"))*".
• Removing quotes may allow a broader search: (((( research site paper ) OR ( research scope paper ))) or ( research write papers ))*.
