Solr

[Joan Moreau]

I shared the errors already so many times (check this mailinling for
"solr" in teh title) 

Contrary to what you say, with SOlr 7.5 and Dovecot git,  I had to
remove the "managed-schema" to make solr respond a bit properly. It
relies on schema.xml 

In order to create the instance, no, it copies  the default config in
the dovecot instance. 

Bottom line, the end results is that the results are either "error :
invalid response" (mostly on Android email client) or no results or
innacurate results (using Roundcube)

Copy the '_default' folder, with all its contents, to a 'dovecot' folder.  In the new dovecot folder, replace the 'managed-schema' file with the file from the Dovecot Wiki
