Hi, Michal.  You might consider using a format that might be actually
adopted by notmuch down the line.  This is sure to set off a protracted
bike-shedding debate, but let me get the ball rolling.

Imagine down the line we are able to index arbitrary user-specified
headers.  Maybe we could adopt a new search prefix of the form:

  x:<header>:<value>

e.g.

  x:list-id:notmuch.notmuchmail.org

I think this would work with the Xapian term prefixing, but I'll let the
Xapian experts comment.

Bike shed away!

jamie.
