fts_squat was deprecated in 2.1. There's a high likelihood it is buggy in a variety of ways in any recent Dovecot release.

With activated fts the search on the inbox folders works expectedly well but any attempt to search anything in any virtual folder leads to the following error. Similarly when attempting "doveadm fts lookup". I also noticed that no search index for the virtual folders gets build - is this expected behaviour?
