dovecot - Sep 2011 - dovecot-virtual folder configuration

Hi all,

Long story short, I'd like to configure a folder containing:

INBOX
(some other folders)

-> unseen emails from these folders + all other emails (also seen) from 
the same thread
-> seen emails from these folders, but only the recent ones + all other 
emails from the same thread


I tried:
#    inthread refs (or (or recent unseen) recent )
     inthread refs unseen
# inthread refs (or unseen (  recent seen) )
#    inthread refs  recent unseen
# inthread refs unseen
#inthread refs recent (or unseen )
# inthread refs (recent seen (or unseen ))
# (inthread refs  (or unseen) recent seen)
#( inthread refs (or (or recent unseen) flagged) )

without success.

Where could I find proper,understandable doc for this?
Could anybody help me on configuring such rule(s) ?

Thanks a lot in adavance,

Pierre

The "other mails from same thread" is still a bit problematic with
virtual folders. From my TODO:

 - virtual: If last message matching INTHREAD rule gets expunged, the rest of
   the thread doesn't go away

First you'll need to create a virtual folder that has all the mails that
you would ever want to see in threads. For example:

virtual/all/dovecot-virtual:
-----
INBOX
Sent
some
other
folders
  all
-----

Then based on that create the virtual mailbox you want:

virtual/newstuff/dovecot-virtual:
-----
virtual/all
  inthread refs or unseen recent
-----
