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