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