Search API Federated Solr

Search API Federated Solr is an open source alternative to the Google Search Appliance and other technologies that index and search across multiple web sites.

Primary features of the module include:

• Indexing of multiple, independent Drupal sites into a single index
• Optional filtering of search results by site
• Standard presentation of search results on all sites
• A standard search block for use on all sites
• Customizable presentation using a single CSS file

Which version should I use?

The 4.x release and branch are Drupal 9 and 10 compatible. Any fuirther development will be done in this branch.

Search API Federated Solr 3.x is a stable release which may still support Drupal 8.

The 2.x release supports Solr 4-6. Support for Solr beneath version 7 is end-of-life. so the 2.x release will only receive security updates and will not be updated for Drupal 9.

Users are encourages to upgrade to 4.x as soon as their Solr instance supports it. See the Search API Solr page for addition information.
