"research while papers" » "research where papers", "research which papers", "research why papers", "research white papers", "research while others", "research while part"
"research what papers" » "research what hampers", "research what players", "research what pages"

Try widening your search to All Fields.

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 white paper"))) OR ((("research while papers") OR ("research what papers")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"research write paper\") OR (\"research white paper\"))) or (((\"research while papers\") or (\"research what papers\"))))".
• Removing quotes may allow a broader search: (((( research write paper ) OR ( research white paper ))) or ((( research while papers ) or ( research what papers )))).
• Adding a wildcard symbol may retrieve word variants: (((("research write paper") OR ("research white paper"))) or ((("research while papers") or ("research what papers"))))*.
