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