• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"improving can performance targets.\") OR (\"improving co performance metrics.\"))".
• Removing quotes may allow a broader search: (( improving can performance targets. ) OR ( improving co performance metrics. )).
• Adding a wildcard symbol may retrieve word variants: (("improving can performance targets.") OR ("improving co performance metrics."))*.
