Perhaps you should try some spelling variations:
"improving lives performance metrics." » "improving lives performance measures.", "improving live performance metrics.", "improving driven performance metrics.", "improving driver performance metrics.", "improving living performance metrics.", "improving civic performance metrics.", "improving civil performance metrics."
"improving loan performance series." » "improving loan performance studies.", "improving loan performance size.", "improving local performance series.", "improving land performance series.", "improving lead performance series."

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("improving loan performance series.") OR ("improving lives performance metrics."))~.
• Removing quotes may allow a broader search: (( improving loan performance series. ) or ( improving lives performance metrics. ))~.
• Adding a wildcard symbol may retrieve word variants: (("improving loan performance series.") or ("improving lives performance metrics."))*.
