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