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