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