• Performing a fuzzy search may retrieve terms with similar spellings: (("based formulation in coding problems") OR ("using coding python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based formulation in coding problems\") OR (\"using coding python python programming\"))*".
• Removing quotes may allow a broader search: (( based formulation in coding problems ) OR ( using coding python python programming ))*.
