That's a really hard way to get introduced to Solr. What about downloading Solr and running one of the built-in examples? Because you are figuring out so many variables at once.
Either way, your specific issue is not in schema.xml (which should be converted to managed-schema on first run, btw, don't have both in the same directory). Your issue is in the solrconfig.xml and it is complaining about schemaless mode missing the default type mapping for when no other rules match. As explained at: https://lucene.apache.org/solr/8_6_0/solr-core/org/apache/solr/update/processor/AddSchemaFieldsUpdateProcessorFactory.html In your linked example, that's the line: <str name="defaultFieldType">strings</str> In latest Solr, it is using the default flag instead, so maybe you ended up not having either. I think the example basically skips all the mapping and creates all fields automatically of type strings. So, you can probably remove all processors apart from add-schema-field in updateRequestProcessorChain definition and reintroduce the defaultFieldType from original example. Hope that gets you where you want. If it does not, don't give up on Solr, just step back a bit and get it working by itself first. Maybe try following my presentation from a while ago: https://www.slideshare.net/arafalov/from-content-to-search-speeddating-apache-solr-apachecon-2018-116330553 , the associated Github repo is at: https://github.com/arafalov/solr-apachecon2018-presentation Regards, Alex.
