The State of Georgia’s Digital Services team (DSGa) supports a network of over 100 websites running on Drupal. Originally built in Drupal 7, DSGa began transitioning to a new Drupal 8 platform in 2019. Until this transition is completed, DSGa is responsible for supporting both Drupal 7 and Drupal 8 sites.
Sites in the network need the capacity to search content from both their own site and other sites, regardless of the version of Drupal being used. While both platforms are hosted on Acquia and use Acquia Search, their Drupal 7 search solution could not incorporate content from the new Drupal 8 sites. This left the DSGa team in an awkward position: either lose functionality while they waited for sites to transition to Drupal 8 or delay the launch of the new platform until all sites were ready.
Fortunately, there was another option. Using the open source Federated Search solution, Palantir collaborated with the DSGa and their development partners to re-launch network-wide search with added functionality in both Drupal 8 and Drupal 7 without any service interruption for site visitors.
