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