I don't know really .. They shouldn't have anything to do with each
others. Although if you also deleted dovecot-uidlist, Dovecot assigns
new UIDs to messages and that might have helped. But if dovecot-uidlist
was there, then I've no idea. If you can reproduce this somehow I'd like
to know.

Dovecot should always auto-heal itself, so it's a bug if it doesn't.

That's how it works currently. With the byte count I meant that it would
cut at the previous (or the next) character after that many bytes. So
for example "abcd" and "åäöå" would be indexed as 4 characters, because
the first takes 4 bytes and the second takes 8 bytes, but then 4 chinese
characters each taking 3 bytes would be cut after 2 or 3 characters. 

None of this affects the actual search results. Only how much disk
space, memory and disk I/O is used when searching.
