How stable is that now? https://wiki.dovecot.org/Plugins/FTS says above: "The following FTS indexers (in preferred order) are supported" but fts-xapian is listed below all others and Solr at the top. Solr fts plugin is developed by dovecot developers therefore an "official" plugin. Xapian is an "unofficial" plugin developed by Joan Moreau. Is the wiki just outdated? Felix -- Christian Kivalo

Dovecot indexes are not actually related to FTS that much. Using FTS usually makes sense since it speeds up IMAP fulltext searches. Aki
solr vs fts
Hi I have a question about tunning dovecot-2.2.36.x Mail was stared in storage via nfs in MAILDIR via /home/us/usern...@domain.ltd/MAILDIR/ I use additionally local dovecot_indexes via SSD disk (/var/dovecot_indexes%h) A few clients have 25K and more e-mail I thinking about use solr like: fts = solr fts_solr = debug url=http://IP:8983/solr/ (solr in external machine) Does it make sense ? use dovecot_indexes and fts ? What is the difference in performance?
