[SOLR] Where is solr-schema.xml?

Hello,

running dovecot 2.3.2.1 on Arch Linux, and installed solr 7.4.0.

According to the wiki, there should be doc/solr-schema.xml, but I cannot find it.

Tried "whereis dovecot": dovecot: /usr/bin/dovecot /usr/lib/dovecot /etc/dovecot /usr/include/dovecot /usr/share/dovecot /usr/share/man/man1/dovecot.1.gz

But I cannot find any xml files using find /usr/{lib,share}/dovecot -name "*.xml"

Kind regards

Peter
