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