Dear Daniel.
Thank you for your kind reply.
Regarding NFS, no, there is nothing like this in my setup.
Deleteing SOLR and recreating it, I did it so many times already.
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 )
I added the fts_enforce following AKi advice.
I removed fts_decoder for the time being.
I don't know where to go now. Dovcot still returning errors and SOlr
still companinig with "Out of range" and other Java errors.
Bottom line, I am back to squat, but as it is not maintained so crashed
also times to times.
I think we should discuss on
(1) Why the damn choice of Solr has been main. As you empahised,
maintainend so many independent software is a pain
(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 ?
(3) If there iare no tangible reason, what about maintaining fts_squat ,
which did the job nicely for years and no complains about.

Joan,
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.
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.
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.

Daniel,
I have done that so any times (deleteing the data folders, recreating the instance, restarting etc...)
But this is really not the issue
The issue is
1 - fts_solr reports errors in the log file (this is a pure dovecot issue) : how to have much more details on what fts_solr sends to Slor server and what does it returns ?
2 - Solr returns properly for a few hours, then starts crashing or responding non-sense after some time
Additionally, is there a doc of fts-squat in order to adjust the code to new releases of dovect ?

I shared the errors already so many times (check this mailinling for "solr" in teh title)
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
In order to create the instance, no, it copies the default config in the dovecot instance.
I'm not a Solr expert by any means but I believe you are incorrect.
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.
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.
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. --
