• If you are trying to use Boolean operators, they must be ALL CAPS: (("((((evidence syntheses) OR (evidence synopsis))) or (evidence synthesis))") OR ("evidence synthese")).
• Removing quotes may allow a broader search: (( ((((evidence syntheses) OR (evidence synopsis))) or (evidence synthesis)) ) or ( evidence synthese )).
• Adding a wildcard symbol may retrieve word variants: (("((((evidence syntheses) OR (evidence synopsis))) or (evidence synthesis))") or ("evidence synthese"))*.
