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