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