If you go to http://mail.gnome.org/archives/ and you search whatever (i.e. "guadec") you will get two problems:
1. "Last modified: 2000-08-06" when it should be obviously a more recent date.
2. The latest results are from the summer of 2004, more or less. This means that a huge amount of mails are not being searched, although you can find them in the MHonArc archives.
I'm not sure whether this is a Namazu bug or a problem of our (big) installation. We have detected this bug since ages but we haven't been able to apply a solution. We hope you can help.
