"research white paper" » "research while paper", "research what paper", "research where paper"
"research later papers" » "research water papers", "research laser papers", "research late papers", "research late paper"
"research state papers" » "research status papers", "research strategy papers", "research station papers", "research staff papers"

• Removing quotes may allow a broader search: (((( research write paper ) or ( research white paper ))) or ((( research later papers ) or ( research state papers )))).
• Adding a wildcard symbol may retrieve word variants: (((("research write paper") or ("research white paper"))) or ((("research later papers") or ("research state papers"))))*.
