Remember that is a final filter. So it says "scrape as many URL's as you can, from you settings, and then when it passes the PR, and OBL filter then apply it."
So remember it uses up alot of resources and then rejects ALL url's that don't meet this criteria.
I think to use this feature you have to use sitelists that you import yourself.
Not really. The program tries to apply the domain filter when finding new targets with search engines. Of course not all search engines support this, but if they do, it will be used.
@Sven - do you have a list of SE's that support this? Or could you add it as an option in the SE list. Like "Use SE's that can search by domain type". Would be very useful.

I'm not sure exactly what a wiki has in the domain name to help find it. Maybe !wiki
