• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational java computer program\") OR (\"by computational python computer program\"))*".
• Removing quotes may allow a broader search: (( using computational java computer program ) OR ( by computational python computer program ))*.
