solr and dovecot-2.2.36.4

Hi Today i try run solr-8.6.0 + dovecot-2.2.36.4 and false

I read https://doc.dovecot.org/configuration_manual/fts/solr/#fts-backend-solr

Where I get schema.xml and solrconfig.xml for this version solr and dovecot ?

I try schema.xml and solrconfig.xml from working solr-6.6.5 (dovecot) "dovecot: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error initializing QueryElevationComponent"
