Solr should support a way to specify fields to exclude in copyField declaration in case source or dest has wildcard

 

Something like

{ "dest": "metadata_all", "source": "* - [_text_]" }

 

or

{ "dest": "metadata_all", "source": "*" }

,

{ "dest": "metadata_all", "source": "_text_", "exclusion": true }
