"research late papers" » "research later papers", "research gate papers", "research state papers", "research late paper", "research white papers"
"research kate papers" » "research katie papers", "research gate papers", "research kati papers", "research state papers", "research later papers", "research waste papers"

• Removing quotes may allow a broader search: (((( research late papers ) or ( research while papers ))) or ( research kate papers )).
• Adding a wildcard symbol may retrieve word variants: (((("research late papers") or ("research while papers"))) or ("research kate papers"))*.
