• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational python computer program\") OR (\"teaching computational 3d example program\"))".
• Removing quotes may allow a broader search: (( using computational python computer program ) OR ( teaching computational 3d example program )).
• Adding a wildcard symbol may retrieve word variants: (("using computational python computer program") OR ("teaching computational 3d example program"))*.
