Perhaps you should try some spelling variations:
"research while papers" » "research where papers", "research which papers", "research why papers", "research white papers", "research while others", "research while pair"
"research while part" » "research where part", "research which part", "research why part", "research chile part"
"research what papers" » "research what hampers", "research what players", "research what pages"

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