Hello, For mobile clients (gmail on Android), I need a server side searching solution. A few months ago, I tried getting Solr to work with Dovecot, but failed. The instructions here https://doc.dovecot.org/configuration_manual/fts/solr/ are quite out of date, they reference Debian 8 and 9 (current version 11), and Solr 7.7 (current version 9.2) My Solr experience is pretty much zero. Questions/Requests:

• Is there a different tool than Solr I should be using for this?
• Does anyone have a recent version of Solr and Debian working?
• If you do, would you be willing to help me?
• I cannot afford much, this is a home mailserver for my wife and I, but I could pay a small consulting fee. I use ansible to deploy the server, I'd be willing to contribute the playbooks somewhere for documentation, or help with the docs. Thanks! John

You can try https://github.com/slusarz/dovecot-fts-flatcurve .

Can you give more details on how Solr didn't work for you? I am using solr myself.

I now updated my Solr to 9.2. It took a little bit more effort, but I'll see if I can update our docs to indicate how you could use Solr 9.

Biggest issue in my mind is that you will need to tell Solr to update it's indexes (somehow) when using version 8 before upgrading to 9. Because the older indexes are no longer compatible with 9.

Other than that, it was pretty simple to get it working in the end.
