Perhaps you should try some spelling variations:
"improving local performance metrics." » "improving local performance contracts.", "improving local performance contract.", "improving social performance metrics.", "improving loan performance metrics.", "improving fiscal performance metrics.", "improving global performance metrics."
"improving thermal performance measures." » "improving maternal performance measures.", "improving rural performance measures.", "improving human performance measures."

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

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