dovecot - Oct 2017 - Solr 7

Before I go down the route of upgrading our main Solr instance from 6 to 7, just
checking if anyone is using Solr 7 with
Dovecot.

SOLR 7 works ok with dovecot. We did not upgrade but indexed from scratch with
7.0.0.

From our experience:

Make sure that you set the default queryResponseWriter to XML on 
solrconfig.xml:

     <queryResponseWriter name="xml"
                          default="true"
                          class="solr.XMLResponseWriter" />

Because the default response type is now JSON instead of XML and I don't
think
dovecot sends a wt=xml to make it explicit.

Also, consider going to 7.0.1 because 7.0.0 could not read indexes from 6.x
versions. As I said we did a reindex so we were unharmed by that bug but just
saw it on the 7.0.1 changelog.

could you please provide more informations about the installation from 
scratch? The documentations I?ve found are all outdated and doesn?t work :(.

Thanks,
