Perhaps you should try some spelling variations:
"global enforcement governance system." » "global efficient governance system.", "global empowerment governance system.", "legal enforcement governance system.", "alabama enforcement governance system.", "law enforcement governance system."
"legal environmental performance metrics." » "legal environment performance metrics.", "legal environments performance metrics.", "local environmental performance metrics.", "legal environmental performance measures."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("global enforcement governance system.") OR ("legal environmental performance metrics."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"global enforcement governance system.\") OR (\"legal environmental performance metrics.\"))*".
• Removing quotes may allow a broader search: (( global enforcement governance system. ) OR ( legal environmental performance metrics. ))*.
