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.

Bottom line, the end results is that the results are either "error : invalid response" (mostly on Android email client) or no results or innacurate results (using Roundcube)

The one on the Wiki is mine...which I'm using now. So it certainly does work - but perhaps there's a setting you have differently from me.

Performing a "create -c dovecot" creates a Solr instance *named* dovecot - that does *not* initialize it with the necessary schema. You need to specify "-d dovecot", with a dovecot configset already setup, to do that.

The other choice is to create the instance as you show, ensure Solr is stopped, delete the "<prefix>/solr/dovecot/data" folder, and copy the managed-schema file to "<prefix>/solr/dovecot/conf". Again, the filename saved in the /conf folder needs to be "managed-schema" - no ".xml" suffix.

If that doesn't work for you - please share the errors.

Hi Daniel,

THere is no need of all this, just the command (on Solr 7.5) "create -c dovecot " is enough

The chema.xml provided on the wiki basically does not work on 7.5

Here the latest one I am working on , but nothing works properly (bad search results, errors in ftp_solr, etc..)

In the Wiki, ( https://wiki.dovecot.org/Plugins/FTS/Solr ), it would nice to stipulate to the reader to type the command :

sudo -u solr /opt/solr/bin/solr create -c dovecot # to create the dovecot instance

before updating the schema.xml .

Also, schema.xml is in /opt/solr/server/solr/dovecot/conf for archlinux users

Additionaly, the url is http://(solr_server):8983/solr/dovecot/ (error in wiki)

After installing Solr, wherever the installation sets up there should a folder similar to:

<your prefix>/solr/server/solr/configsets

If you look there, you'll probably see folders like '_default' and 'sample_techproducts_configs'. I haven't played with the 'techproducts' sample. Copy the '_default' folder, with all its contents, to a 'dovecot' folder. In the new dovecot folder, replace the 'managed-schema' file with the file from the Dovecot Wiki

https://wiki.dovecot.org/Plugins/FTS/Solr?action=AttachFile&do=view&target=solr-7.x-schema.xml

after that, you should be able to run 'solr /opt/solr/bin/solr create -c dovecot' to create the instance. If things still don't work let us know.

The schema is one I've tweaked and updated during my own migrations since Solr 3.3. It's possible there's something else in my config that needs documenting - but having experienced Solr search against my mailstore I never want to be without it.
