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