Solr support for WordPress and the Solr Power plugin will reach end of life on January 11, 2027. After this date, Solr-based search will no longer be available for WordPress sites on the platform.
What's changing?
Solr 3 is a legacy search technology that is being retired in favor of modern alternatives. Sites currently using Solr 3 with the Solr Power plugin will need to migrate to a supported search solution before the end-of-life date.
Recommended alternatives
Pantheon customers
We recommend migrating to Elasticsearch, now available as a Beta add-on for WordPress sites on Pantheon. Elasticsearch offers improved search relevance, real-time search-as-you-type, WooCommerce support, and more. See the Elasticsearch for WordPress Beta announcement for details.
Other options
If Elasticsearch is not the right fit for your site, consider these third-party search solutions:
- SearchWP — A WordPress-native search plugin that enhances the default WordPress search without requiring an external search service.
- Algolia Search — A hosted search API that provides fast, relevant search results with advanced features like typo tolerance and faceted filtering.
What you need to do
- Identify any WordPress sites currently using the Solr Power plugin.
- Choose a replacement search solution.
- Complete your migration before January 11, 2027.
