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