• If you are trying to use Boolean operators, they must be ALL CAPS: (("rapid response depot: systematic review") OR ((("Rapid response report: systematic review") OR ("Rapid responses report: systematic review")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"rapid response depot: systematic review\") or (((\"Rapid response report: systematic review\") OR (\"Rapid responses report: systematic review\"))))".
• Removing quotes may allow a broader search: (( rapid response depot: systematic review ) or ((( Rapid response report: systematic review ) OR ( Rapid responses report: systematic review )))).
• Adding a wildcard symbol may retrieve word variants: (("rapid response depot: systematic review") or ((("Rapid response report: systematic review") OR ("Rapid responses report: systematic review"))))*.
