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