dovecot fts hangs on search

Tue May 1 09:22:26 EEST 2018

Hello,

I am trying to use Doevecot fts, with solr the script provided.

To rebuild the index, I use the command:
doveadm -D index -u mirina 'inbox'

To rescan, I use: doveadm -D fts rescan -u mirina

But when I do a search, with doveadm, the program hangs:

doveadm -D search -u mirina text Madagascar

When I do the search with an imap client, I have this error after a long 
timeout:

My 10-master.conf:

service decode2text {
   executable = script /usr/local/bin/decode2text.sh
   user = dovecot
   unix_listener decode2text {
     mode = 0666
   }
}

And my 90-plugins.cof:
   # Add dovecot fts config
   fts = solr
   fts_autoindex = no
   fts_solr = url=http://localhost:8080/solr/ debug
   fts_decoder = decode2text

Am I doing anything wrong?

Thanks for your help.
