Anyway, I run tcpdump to see network activity between dovecot and solr:

no output also from doveadm.

Noticed that dovecot.index.log reapears in user mail root if deleted.

After some fiddling around, come in to conclusion that doveadm fts 
rescan is nothing to do about real indexing. So, it is working.
Anyway, now thinking about what really differs when fts is used vs not 
used. 1 argument is speed, what else?

"doveadm fts rescan" resets pointers but does not itself trigger a 
re-index.  But it makes the next actual index scan the full mailbox.


The whole point of FTS is "full-text-search".  So if you don't use it - 
you don't need it.  But when large mailboxes are involved, searches 
involving solr indexes are extremely fast compared to non-fts searches.

Solr is built for indexing, what else do you expect?



Stemming for example, but it's not critical anyway, as my language doe's 
not have publicly available stemming dictionary/algorithm.
