Subject says all. Timo, would you write something up where the world will find it? Also, it would be great if doveadm fts was covered in the doveadm manpage.
It runs the Lucene's optimize function with fts-lucene backend. Does nothing with others. Basically I think it just gathers multiple Lucene index files together and packs them into a single file, dropping all deleted data (Lucene documentation has more details I think). Similar to what "doveadm purge" does to mdbox files. fts-lucene runs the optimize also internally automatically once in a while, so I'm not sure if that doveadm command should necessarily even exist.
I think the answer lies in your perception of benefits vs maintainance (including documentation) costs... ;-)
Based on the awesome explanation I just gave, I wouldn't mind if someone converts something based on it to a man page patch!
