Perhaps you should try some spelling variations:
"improving crop performance metrics." » "improving crop performance contracts.", "improving crop performance measures.", "improving crop performance contract.", "improving poor performance metrics.", "improving job performance metrics.", "improving city performance metrics.", "improving co performance metrics.", "improving macro performance metrics.", "improving food performance metrics."
"emerging export performance series." » "emerging export performance reviews.", "emerging export performance review.", "emerging export performance targets.", "leveraging export performance series.", "emerging post performance series.", "improving export 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: (("emerging export performance series.") OR ("improving crop performance metrics."))~.
• Removing quotes may allow a broader search: (( emerging export performance series. ) or ( improving crop performance metrics. ))~.
• Adding a wildcard symbol may retrieve word variants: (("emerging export performance series.") or ("improving crop performance metrics."))*.
