yes - that is the first article we were checking but this is on Solr 6:(

I am on a project to integrate the latest Solr version (Solr 9) with AEM 6.5. It looks like the current Adobe document integration guide is on Solr 6. Anyone knows some good reference for Solr 9 and AEM 6.5? All I find are old Solr version only..Thanks!
