I'm using the unique flag when I index a site. Yet when you do a
search, duplicate sites are listed in the find. Do I have to do something
special to use the unique flag?
Make sure you use -unique before walking any pages.
It must be active before any walks for it to work. If you turn it
on later it won't work right. See http://www.thunderstone.com/gw25man/node44.html
