dovecot - Nov 2012 - Solr 4.0 - lucene - FTS

Hi Timo,

As one who is interested in implementing FTS sometime in the future, I'm 
curious about what is in store as far as improvements go...

Specifically, any plans for implementing immediate/automatic index 
updates at delivery time? The lack of automatically updated indexes is 
one downside for its implementation...

Also, does the release of Solr 4.0 mean anything for the lucene library 
used by dovecot?

Thanks,

Nothing really prevents from adding that very easily .. I guess it would need a
new setting, which is always the most annoying part of small changes. :) I think
it would have to have a setting equivalent to doveadm index -n parameter, which
allows indexing most users, except those who pretty much never read their
emails. So with doveadm index -n 1000 you could set that if the mailbox's
\Recent count is over 1000, don't index the mailbox. So .. hmm. I guess two
settings would be cleaner:

plugin {
  fts_autoindex = yes
  fts_autoindex_max_recent = 1000
}

Or maybe there's a better name than "autoindex" for this feature.
SEARCH always autoindexes anyway.

No, fts-lucene and fts-solr are separate backends. But I do have some small
plans to add a few more features to fts-solr.
