I'm looking into improving email search speed on my Dovecot server by integrating with Solr. On my servers, I try to keep as much of my software as possible installed from the repositories for ease of updating.
I've noticed that there's a dovecot-solr package in the repositories, which made me pretty hopeful. There is no solr package, but I did see a solr-common package that appears to pull in a lot of the Solr prerequisites, including tomcat-solr (which pulls in tomcat in full). I installed that.
Now I'm trying to get an impression from the various documentation I've been able to find on where to proceed from there. I see references to accessing "" on my server, but it doesn't appear to be accepting connections on that port. Tomcat is running. I've also seen references to a solr binary, but I can't find any packages that provide that file.
Is it possible to install Solr completely from repositories? If not, what's the purpose of the solr-common package? Does it simplify the outside-repository install at all? If so, is there documentation on how to complete an install of Solr on Ubuntu Server 18.04 starting with what's available in the repositories?
