Yesterday I upgraded my Solr install for dovecot from 8.11.2-SNAPSHOT to 
10.0.0-SNAPSHOT.  It is still working and the config did not need 
further changes from what I already had.

I have been customizing my solrconfig.xml and managed-schema files ... I 
had made the change to CaffeineCache quite a while back.  I have also 
changed the analyzer chain in the schema to use a contrib component, so 
my config won't be directly usable -- it requires loading some extra 
jars.  When I upgraded, I did need to change the extra jars that were 
loaded.

I can come up with a new config that should work in 8.x, 9.x, and the 
current dev branch by almost anyone.

I should probably see if I can write some end to end instructions for 
installing Solr and configuring dovecot to use it.  Something that is 
missing from the current instructions is how to initiate a FULL reindex 
of all data in the dovecot install.

Thanks,
Shawn
