metatag_search_gov
No security coverage
This module works with the Metatag module to add the searchgov_custom* fields that search.gov uses to allow for additional fields for their Search Filters (Faceted Search).
Probably if other custom fields unique to Search.gov those will also be added to this module.
This module was specifically written as the Metatag Custom module will list multiple Meta tags instead of multiple items in the one tag separated by commas like Search.gov wants.
Features
Adds the ability to configure Metatag to use the searchgov_custom1, searchgov_custom2, and searchgov_custom3 fields.
Post-Installation
Navigate to /admin/config/search/metatag/node#edit-search-gov and add tokens for the three custom meta tags..
