• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"appendix mathematical science\") or (((\"appendix mathematics science\") OR (\"appendix mathematische science\"))))".
• Removing quotes may allow a broader search: (( appendix mathematical science ) or ((( appendix mathematics science ) OR ( appendix mathematische science )))).
• Adding a wildcard symbol may retrieve word variants: (("appendix mathematical science") or ((("appendix mathematics science") OR ("appendix mathematische science"))))*.
