I just remembered (and olly confirmed) that there is some work in
progress on adding file sizes to the xapian query parser. Finishing that
would benefit more people, and allow the feature you want in notmuch
with less code in notmuch. Maybe you could have a look and see if it's
practical to finish this off (or consult with the original student who
seems to have abandonded it, but maybe not).

When I take a second look at that pull request, it's more a layer on top
of the series proposed for notmuch, to provide human readable units.
It (and the omega file size indexing it extends) nonetheless might
be interesting for you.
