in dovecot config, i've added

	plugin {
		fts_tika = http://127.0.0.1:9998/tika/
	}

and

	log_debug = (category=fts-flatcurve OR category=fts-tika)

on message receipt, I see verbose logs for fts-flatcurve, as expected, but not a
trace of output from fts-tika, in dovecot logs

how to correctly turn on debug/verbose logging for fts-tika use in/by dovecot?

mail_debug = yes

This turns on HTTP debugging for the outgoing Tika requests.

Unfortunately, Tika has not yet been converted to events/categories with the
ability to more granularly enable debugging just for this component.

It's probably easier to just look at tika's debugging logs.  The default
log level (at least in Tika 2.3) will output an INFO line for every attachment
indexed:

INFO  [qtp235162442-22] 16:15:19,905
org.apache.tika.server.core.resource.TikaResource /tika (text/calendar)
