Since is not mark as "stable" you cannot know if somethings will be changed with the next commit, you must built it from git and rebuild dovecot from source in order to add some feature (icu, stemmer, textcat) that are not present in the official repo. More, in my test is not clear how will be big the "fts-flatcurve" database directory, with the latest dovecot (2.3.18) and fts-flatcurve the xapian database is more than double of the Maildir/ and I don't know why (I'm testing with an old xapian 1.4, I will try to upgrade it). I found some issue during the switch from fts-solr to fts-flatcurve that require to delete some dovecot.* file in order to restore the correct result in the SEARCH. I have not understand if Virtual mailboxes works fine. So ready for a small environment where you can delete all dovecot index files is something is not clear/working fine but not ready for a medium/large environment where you need, for example, a well defined procedure for migration from one fts plugin to another. But I'm still testing it and I hope to see a stable version for it as soon as possible. -- Alessio Cecchi Postmaster @http://www.qboxmail.it https://www.linkedin.com/in/alessice
Re: Lucene support for FTS - EOL date.
Hi! fts-lucene and fts-squat are going to be removed in next major release, which is going to be released this year. We are planning to add xapian based replacement for lucene.

I'm trying to find out how much time I have.

If you use Lucene the most "simple" switch is to the new fts-flatcurve and Xapian: https://github.com/slusarz/dovecot-fts-flatcurve I'm testing it and is almost "ready for production".

Re: Lucene support for FTS - EOL date.
We are talking about the large-scale commercial use of Dovecot + lucene as an FTS. MIgration to SOLR is some kind of challenge that will take some time. I'm trying to find out how much time I have. On the one hand i would like to use only the newest version of Dovecot but on the other hand i'm not able to switch fts from lucene to solr in the near future sob., 5 lut 2022 o 21:26 Stuart Henderson napisał(a): > On 2022-02-05, Jacek Grabowski wrote: > > Ok but I have to know the date (approximate) when support for lucene will > > be removed completely from dovecot. > > Does anyone know when this will happen?

If dovecot-fts-lucene is currently working for you then dovecot-fts-flatcurve might be a good alternative. (Another option is to not update. You might think that's a bad idea, but with fts-lucene you already on something which is outdated so that isn't new).
Re: Lucene support for FTS - EOL date.
Ok but I have to know the date (approximate) when support for lucene will be removed completely from dovecot. Does anyone know when this will happen? It is scheduled in some version in the future maybe? pt., 4 lut 2022 o 22:57 Michael Slusarz napisał(a): > On 02/04/2022 4:03 AM Jacek Grabowski wrote: > > Actually on the https://doc.dovecot.org/configuration_manual/fts/lucene/ > site we can read about lucene fts plugin: > > "This plugin is no longer maintained in Dovecot (as of 2.3+) and will be > removed in the future." > > Does anyone know about approximate EOL date for lucene plugin support in > Dovecot? > > Realistically ... many years ago.

Lucene support for FTS - EOL date.
Hello Actually on the https://doc.dovecot.org/configuration_manual/fts/lucene/ site we can read about lucene fts plugin: "This plugin is no longer maintained in Dovecot (as of 2.3+) and will be removed in the future." Does anyone know about approximate EOL date for lucene plugin support in Dovecot? -- Pozdrawiam. Jacek Grabowski.
