i don't believe tags are appropriate for this use -- the growing
convention is to use properties for automated notes like this, and you
can see from the series that this is the case:

+	notmuch_message_add_property (message, "index.repaired", "mixedup");

you should be able to do that with:

     notmuch search property:index.repaired=mixedup

does that satisfy your concerns?
