• 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 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 what papers\"))))".
• Removing quotes may allow a broader search: (((( research scope paper ) OR ( research scopus papers ))) or ((( research white 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 what papers"))))*.
