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