Hello: Following the discussion on the ksummit list [1], I wanted to give someone a query they could use to keep an eye on any new threads. Is there a xapian query that can be used to effectively say "return just top-level messages and exclude any follow-ups"? It's not quite as simple as "s:* AND NOT s:Re:" because we also want to exclude threaded patches. Some kind of equivalent of "any messages without an in-reply-to/references header"?
