• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder detection model coding program\") OR (\"and introduction python python programming\"))~".
• Removing quotes may allow a broader search: (( coder detection model coding program ) OR ( and introduction python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder detection model coding program") OR ("and introduction python python programming"))*.
