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