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