<p>Hi Daniel,</p>
<p>I am on Archlinux. Anyway, I adapted the scripts.</p>
<p>2 questions:</p>
<p>1 - It looks like we are not on the same version . I am on 7.5.0. Which version are you running ?</p>
<p>2 - Your conf shows that you let managed-schema but deleted schema.xml. What is the meaning of each ?</p>
<p>Thank you</p>
<p><br /></p>

<p>Joan,</p>
<p>The reason for dropping squat, I'm assuming, is that Lucene and Solr potentially provide superior features & performance and as they are 3rd-party libraries & apps it reduces the maintenance responsibilities and let's the Dovecot team focus on mail server specific stuff - and let others focus on FTS. There is a *huge* difference between a functional Solr setup & squat - and if I'm able to get it working we should be able to get you there as well.</p>
<p>I don't recall what OS you're running - I'm on Ubuntu 18.04. My Java version is OpenJDK 10.0.2. Attached is my complete Solr config. Try one more time - stop the server, delete the data folder, unpack the attached into the conf folder - and restart. I also have</p>
<p><br /></p>
/etc/default/solr.in.sh:<br />SOLR_OPTS="$SOLR_OPTS -Dsolr.autoSoftCommit.maxTime=3000"<br />SOLR_OPTS="$SOLR_OPTS -Dsolr.autoCommit.maxTime=60000"<br />SOLR_PID_DIR=/run/solr<br />SOLR_HOME=/usr/local/lib<br />
<p>Adjust the above folders as appropriate - or don't use them at all if you're using the defaults.</p>
<p><br /></p>
/etc/systemd/system/solr.service:<br /># put this file in /etc/systemd/system/ as root<br /># below paths assume solr installed in /opt/solr, SOLR_PID_DIR is /data<br /># and that all configuration exists in /etc/default/solr.in.sh which is the case if previously installed as an init.d service<br /># change port in pid file if differs<br /># note that it is configured to auto restart solr if it fails (Restart=on-faliure) and that's the motivation indeed :)<br /># to switch from systemv (init.d) to systemd, do the following after creating this file:<br /># sudo systemctl daemon-reload<br /># sudo service solr stop # if already running<br /># sudo systemctl enable solr<br /># systemctl start solr<br /># this was inspired by <a class="moz-txt-link-freetext" href="https://confluence.t5.fi/display/~stefan.roos/2015/04/01/Creating+systemd+unit+(service)+for+Apache+Solr" target="_blank" rel="noopener noreferrer">https://confluence.t5.fi/display/~stefan.roos/2015/04/01/Creating+systemd+unit+(service)+for+Apache+Solr</a><br />[Unit]<br />Description=Apache SOLR 7.5.0<br />After=syslog.target network.target remote-fs.target nss-lookup.target systemd-journald-dev-log.socket<br />Before=multi-user.target graphical.target nginx.service dovecot.service<br />Conflicts=shutdown.target<br />[Service]<br />LimitNOFILE=65000<br />User=vmail<br />Group=mail<br />ExecStartPre=/bin/mkdir -p /run/solr<br />ExecStartPre=/bin/chown -R vmail.mail /run/solr<br />PermissionsStartOnly=true<br />PIDFile=/run/solr/solr-8983.pid<br />Environment=SOLR_INCLUDE=/etc/default/solr.in.sh<br />ExecStart=/opt/solr/bin/solr start<br />ExecStop=/opt/solr/bin/solr stop<br />Restart=on-failure<br />RestartSec=15s<br />TimeoutStopSec=30s<br />[Install]<br />WantedBy=multi-user.target graphical.target dovecot.service<br />
<p>If you don't use systemd disregard - but see if any of the above applies for your setup.</p>
Let me know what happens. I agree this can be a mortal pain to setup - but it's worth it.<br />

<p>Dear Daniel.</p>
<p>Thank you for your kind reply.</p>
<p>Regarding NFS, no, there is nothing like this in my setup.</p>
<p>Deleteing SOLR and recreating it, I did it so many times already.</p>
<p>I started with *your* setup in the first place, as FTS_squat (which actually works very well and very straightforward, I have no clue why going for SOlr which is just a pain and not maintaining squat), and it leads to totally funny results (for instance, I type "emirates" in my "Air Companies" subfolder and get a lot of results .. but of competing companies :D )</p>
<p>I added the fts_enforce following AKi advice.</p>
<p>I removed fts_decoder for the time being.</p>
<p>I don't know where to go now. Dovcot still returning errors and SOlr still companinig with "Out of range" and other Java errors.</p>
<p>Bottom line, I am back to squat, but as it is not maintained so crashed also times to times.</p>
<p><br /></p>
<p>I think we should discuss on</p>
<p>(1) Why the damn choice of Solr has been main. As you empahised, maintainend so many independent software is a pain</p>
<p>(2) If there is a real reason why going for SOlr, how to have a working (i.e. getting the right results to the end user) setup ?</p>
<p>(3) If there iare no tangible reason, what about maintaining fts_squat , which did the job nicely for years and no complains about.</p>

<p>Joan,</p>
<p>I understand and sympathize with your frustration - trying to get multiple applications to work together, particularly given the lack of documentation for some of them, can be extremely challenging. That said, I suggest you consider an alternative viewpoint. Frequently being misunderstood myself I apologize in advance if I'm reading you wrong - but it appears your view towards the situation is there is a bug in Dovecot related to this problem. That may well be - but I generally approach these matters from the assumption that *I* made the error in configuration and go from there. I'm not an official rep for any product nor claim to be any form of expert in these matters - but I do have a working setup and I'd like to help you if I can. If you're willing to - take a deep breath and let's try starting over.</p>
<p>Looking back through your emails there were two items that stood out - your Dovecot config has two settings I don't use: "fts_decoder" and "fts_enforced". I also asked you earlier whether or not NFS is involved here and I didn't see an answer - please clarify.</p>
<p>I suggest you try once more: delete Solr completely. Re-install per the directions and use *my* managed-schema. Also comment out the Dovecot directives for "fts_decoder" and "fts_enforced" so you're closer to my setup. Try running again and then post back - I'll do what I can. Based on the fact that Dovecot+Solr 7.5+my schema is working for me leads me to believe we can get it working for you as well.</p>

<p>I shared the errors already so many times (check this mailinling for "solr" in teh title)</p>
<p>Contrary to what you say, with SOlr 7.5 and Dovecot git, I had to remove the "managed-schema" to make solr respond a bit properly. It relies on schema.xml</p>
<p>In order to create the instance, no, it copies the default config in the dovecot instance.</p>

<p>I'm not a Solr expert by any means but I believe you are incorrect.</p>
<p>As of Solr 5.x the managed-schema file is the primary method for configuration. The method I detailed previously for setting up a config helps automate creating new Solr instances - but as I stated you can either setup a Solr template and then create the instance from that or create an instance using the default template and then adjust it.</p>
<p>The part that you *must* do after creating from the default template is stop the server, delete the entire "<prefix>/solr/dovecot/data" folder, then install the correct managed-schema file, then restart the server. The server will not function with mismatched schema/data.</p>
<p>If you'll try that - explicitly "rm -rf <prefix>/solr/dovecot/data", copy the managed-schema file into the conf folder, and restart - things will either work or there's something else that needs correction.</p>
