• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code teaching conceptions algorithms complexity\") OR (\"_ python python python programming\"))".
• Removing quotes may allow a broader search: (( code teaching conceptions algorithms complexity ) OR ( _ python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("code teaching conceptions algorithms complexity") OR ("_ python python python programming"))*.
