Perhaps you should try some spelling variations:
research white » research write, research what, research where
research while » research where, research which, research what
white papers » white paper, state papers, late papers
write paper » white paper, written paper, writing paper
waste paper » white paper
while pair » while part

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