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