• Removing quotes may allow a broader search: (( ((supply grid) OR (support grid)) integration efforts. ) OR ( supply data integration series. )).
• Adding a wildcard symbol may retrieve word variants: (("((supply grid) OR (support grid)) integration efforts.") OR ("supply data integration series."))*.
