Considering two crashing bugs, which have got no response (https://sourceforge.net/tracker/?func=detail&aid=3587525&group_id=80013&atid=558446 and https://sourceforge.net/tracker/?func=detail&aid=3592291&group_id=80013&atid=558446) and the lack of activity in its Git repository, I am inclined to think that CLucene's current release series (e.g. 2.3.3.4) should be considered unsuitable for serious use (including with Dovecot).
I haven't heard of any big problems in a couple of large installations. Maybe the problems exist only in OSX and not in Linux?..
I'm going to try CLucene 0.9.21, which they claim has been "proven to be stable over time" (see http://clucene.sourceforge.net), and see how it works out.
Probably not that easy to port the current fts-lucene to use it.. At least I think you need to remove the filtering features.
I wonder if there's a future envisioned for FTS with Dovecot that's suitable for small installations (i.e. doesn't require a Solr server) and has a good chance of correctness and stability?
You could try porting it into luceneplusplus. I've thought about it a few times but haven't had time to try. https://github.com/luceneplusplus
