Dovecot supports several indexers to allow for fast full text searching. Dovecot recommends using Apache Solr through the Dovecot plugin fts_solr
On a usual Debian-based system, one would install this plugin through the package dovecot-solr
and call it a day. But Plesk ships its own version of dovecot (plesk-dovecot
) without Solr support, which conflicts with dovecot-solr
.
The obvious solution to this is to purge Plesk from your system, but that might not be possible.
But, you can of course build the fts_solr
plugin manually.
You shouldn’t do this, unless you have to. Stuff will break.
