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