No it doesn't, but it probably could do with a little clever scripting
to expire the right index pages before each run.
In addition, one of the mods made in the version we are using is the
addition of an XML feed to the indexer - John (the guy responsible for
the port) is keen for me to use this for far more efficient indexing of
the archives, however I have yet to do this mainly because it requires
hacking mhonarc about to output the XML data.

We don't have those fields, but the XML feed was originally written for
indexing data from online catalogues and has added fields like price.
I'd be surprised if others couldn't be added as well.
