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