On ns7 the upstream dovecot
package is compiled against the clucene
library. It’s easy to enable the Lucene index that should speed up the IMAP full-text search feature. More info: http://wiki.dovecot.org/Plugins/FTS
Please, check it out /cc @quality_team
Is it really that fast?
I think we should enable the fts_autoindex=yes
option, as documented on Dovecot’s wiki. However to evaluate this feature properly I would need a real-world mail server (or a copy of it at least) with big mailboxes, so I opted for the more conservative setup at the moment. What do you think?
