• If you are trying to use Boolean operators, they must be ALL CAPS: (((("research scope paper") OR ("research scopus papers"))) OR ((((("research white papers") OR ("research write papers"))) OR ("research what papers")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"research scope paper\") or (\"research scopus papers\"))) or (((((\"research white papers\") OR (\"research write papers\"))) or (\"research what papers\"))))".
• Removing quotes may allow a broader search: (((( research scope paper ) or ( research scopus papers ))) or ((((( research white papers ) OR ( research write papers ))) or ( research what papers )))).
• Adding a wildcard symbol may retrieve word variants: (((("research scope paper") or ("research scopus papers"))) or ((((("research white papers") OR ("research write papers"))) or ("research what papers"))))*.
