Only offers a solr-7.7.0 solrconfig.xml, does it apply to solr-8.0.0?

dovecot-2.3.5.2 and the latest solr-8.0.0.

It seems XMLs do not match each other. How can I fix this problem？

Thanks.

Thanks, I used solr-config-7.7.0.xml as a replacment, it works.

I'll compare solr-schema-7.7.0.xml with dovecot-2.3.5.2/doc/solr-schema.xml and find out the difference.

Thanks.

If the config was actually designed for 7.7, then it will work in 8.0. If it was designed for 5.x or 6.x, there's a chance it won't work.

It sounds like you have a solrconfig.xml file and a schema file that are not matched to each other.

The schema file found here looks to me like it will work in 8.0:

https://raw.githubusercontent.com/dovecot/core/master/doc/solr-schema-7.7.0....

I think instead of using a solrconfig.xml that comes with Solr, you should be using the one made for dovecot:

https://raw.githubusercontent.com/dovecot/core/master/doc/solr-config-7.7.0....

I do see a potential problem with that config, though ... there is config that sets the df parameter (default field) to a field named "_text_" (with underscores) ... this field does not exist in the schema.

Thanks, Shawn
