dovecot - Oct 2015 - doveadm-search-query pattern format

Hello,

the doveadm-search-query documentation specifies a 'pattern'  for many
search keys. Unfortunately it does not mention the format specification of this
pattern (special characters, wildcards, ...). I'm using dovecot 2.2.9 but
also searched the current documention on dovecot.org.

Where can I find further documentation concerning the exact specification of the
pattern format?

Well, it's basically copying the IMAP standard here, which specifies that
searching happens with substring matching. Although if you have full text search
enabled, it may be matching only full words. In any case it's just a text
string and there is no wildcard support, so maybe "pattern" is the
wrong word..
