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