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