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