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