    I just discovered and starting using notmuch this week, so I'm not
    entirely familiar with the project yet.  I had suspected there might
    be more work :)  I'll look into the "database feature".

    My other thought was to just index the content-type with the
    attachment prefix.  This would have made the first search that I
    attempted (without reading the docs/source) work
    (e.g. attachment:text/calendar or attachment:application/ics).

    Is this preferred to adding a new search term?

    I'll make that change.

    I don't use zsh, but I'll look into what's needed.

    Agreed.
