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