Different emails found between 'mu find ...' and `(mu4e--server-call-mu `(find...))` on changing flags on emails about mu HOT 3 CLOSED

Ah, so for speed reasons, Xapian batches up writes to disk... if you want make sure results are written to disk (and visible by external processes), you can do something like pkill -SIGUSR1 mu when you need it. This will terminate the mu process but mu4e restarts it automatically when needed.

How much delay are you seeing? In most cases it shouldn't take more than a few seconds, but if you're indexing as well, it can take a bit longer.

I have tested without indexing, just with M-x mu4e-headers-mark-for-untrash (or does it index internally?).

The emails take minutes to show up in mu find again. I really don't mind a few seconds, but right now, I am waiting about 5 minutes and the 3 sendtestemail emails are still not appearing in mu find.

I also updated the index, downloaded new emails, etc - they don't show up. I know that they will reappear, but I don't really understand the trigger yet.

Since I really wanted to have this going for my application, I am now advising mu4e~headers-found-handler and mu4e~headers-append-handler. In there I append the emails - and it always returned proper results. Still, using mu find could be a bit nicer ;)
