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