Perhaps you should try some spelling variations:
"research status papers" » "research strategy papers", "research studies papers", "research status paper", "research states paper", "research status matters"
"research state papers" » "research strategy papers", "research station papers", "research stem papers", "research staff papers"
"research study papers" » "research study paper", "research study panels", "research student 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 state papers") OR ("research study papers"))) OR ("research status papers")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"research state papers\") OR (\"research study papers\"))) or (\"research status papers\"))".
• Removing quotes may allow a broader search: (((( research state papers ) OR ( research study papers ))) or ( research status papers )).
• Adding a wildcard symbol may retrieve word variants: (((("research state papers") OR ("research study papers"))) or ("research status papers"))*.
