Hi Nathan, AEM does not support Solr 8x for oak indexes due to
non-backwards compatible schema changes. The crux is the underlying
version of Lucene used within AEM (4.7.1).AEM 6.5.6 actually uses Solr
6.6.6 [1][2] -- which may work with 7.x Solr in a limited way. If you're
using Solr as an SRP (Storage Resource Provider) in conjunction with
Mongo then you should be able to use whatever you want. [1] --
