• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computations using computer program\") OR (\"using contour from python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computations using computer program ) OR ( using contour from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computations using computer program") OR ("using contour from python programming"))*.
