Some of our SearchStax Managed Search service clients have expressed concern about Solr/Sitecore compatibility due to two factors:
- Apache recently announced that Solr 8.x has reached its end-of-life.
- Solr 9 is not known to be compatible with Sitecore.
What action should operators of Sitecore/Solr/SearchStax systems take in the face of this uncertainly?
At present (December 2024), Sitecore suggests remaining with compatible versions of Solr 8.x. For Sitecore 10.3 and 10.4, that means Solr 8.11.2. Solr versions 8.11.3 and 8.11.4 are thought to be compatible but are not certified.
See Sitecore’s compatibility page for the latest updates on this situation.
