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