Perhaps you should try some spelling variations:
"research written papers" » "research within papers", "research writing papers", "research twitter papers", "research written paper", "research written patterns"
"research write papers" » "research white papers", "research site papers", "research waste papers", "research white paper"
"research late papers" » "research later papers", "research gate papers", "research kate papers", "research late paper", "research state papers", "research white papers"

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