Perhaps you should try some spelling variations:
"research white paper" » "research write paper", "research what paper", "research site paper"
"research where paper" » "research what paper", "research work paper", "research why paper", "research where proper", "research where apex", "research where peter"
"research while others" » "research which others", "research what others", "research why others"

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