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