However, Solr crashes and Dovecot plugin ftS_solr returns multitude of errors

Dec 09 09:21:09 imap(jom@grosjo.net)<3349><DiRnXpN8Lux/AAAB>: Error: fts_solr: received invalid uid '0'
Dec 09 09:21:10 imap(jom@grosjo.net)<3349><DiRnXpN8Lux/AAAB>: Error: fts_solr: received invalid uid '0'

And returns are totaly funny (keywords not presentin teh results)

I am back to fs_squat....

After some testsing, I managed to get proper functionning

- The schema.xml is attached below (quite different from the one provided on teh wiki) (in bold the core differences) (NGramFilterFactory is the class that replace the fts_squat "partial=3 full=15", everything else is just a big hammer to smash a tiny fly)

- One need to remove the "managed-schema" file in the {prefix}/server/solr/dovecot/conf.

- One need to remove everything under {prefix}/server/solr/dovecot/data/

- The {prefix}/server/solr/dovecot/conf/solrconfig.xml is as below (see diff)

 

- Restart Solr

 

- my dovecot.conf is :

fts = solr
fts_autoindex = yes
fts_enforced = yes
fts_decoder = decode2text

fts_solr = url=http://(SOLR SERVER):8983/solr/dovecot/
