Perhaps you should try some spelling variations:
"global environment performance series." » "global environmental performance series.", "global environmental performances series.", "global investment performance series.", "global environment performance metrics.", "global environment performance review.", "global environment performance targets."
"local government performance reviews." » "local environmental performance reviews.", "local government performance review.", "local government performance reports.", "local government performance risks."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("global environment performance series.") OR ("local government performance reviews."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"global environment performance series.\") OR (\"local government performance reviews.\"))*".
• Removing quotes may allow a broader search: (( global environment performance series. ) OR ( local government performance reviews. ))*.
