Hi,

I have setup dovecot 2.3.5.1 with solr 7.7.1
Everything seems to be working so far except that solr doesn't index a single message.
Solr is running, the web api can be accessed, I see the dovecot core there, but with zero docs.

If I trigger a "body" search from Thunderbird solr is responding and searching, but hitting 0 of course.

Looks like that : 2019-04-14 19:57:42.789 INFO  (qtp898557489-40) [   x:dovecot] o.a.s.c.S.Request [dovecot]  webapp=/solr path=/select params={q={!lucene+q.op%3DAND}body:foobar&fl=uid,score&sort=uid+asc&fq=%2Bbox:925efe067ac8a35ce1430000828c97da+%2Buser:xxx@xxx.net&rows=2&wt=xml} hits=0 status=0 QTime=2

Everytime a new message comes in indexer-worker is working but indexing 0.

Looks like that : 2019-04-14T19:39:36.887817+02:00 riot dovecot: indexer-worker(xxx@xxx.net)<31697><3pDsLlhws1zMewAAgoyX2g:vb2mNFhws1zRewAAgoyX2g>: Indexed 0 messages in INBOX

A "doveadm fts rescan" just brings up this message : "Fatal: Unknown command 'fts', but plugin fts exists. Try to set mail_plugins=fts"

Have you tried to add

mail_plugins = $mail_plugins fts fts_solr to config
My dovecot settings are :
plugin {
    sieve_plugins = sieve_imapsieve sieve_extprograms
    sieve_before = /var/vmail/sieve/global/spam-global.sieve
    sieve = file:/var/vmail/sieve/%d/%n/scripts;active=/var/vmail/sieve/%d/%n/active-script.sieve

    ###
    ### Spam learning
    ...
   
    sieve_pipe_bin_dir = /usr/bin
    sieve_global_extensions = +vnd.dovecot.pipe

    fts = solr
    fts_autoindex = yes
    fts_solr = url=http://localhost:8988/solr/dovecot/ debug

    ...
}

I don't know what to do or what I am doing wrong because solr is responding as said. Also the data directory of the core is empty.
If I should provide more information please tell me which, it's my own server so I have access to everything

Can anyone please help with that??

Thanks.
If the suggested change does not help, send doveconf -n
