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.
