Do you think that these filters should be set in your preferences, or using the "refine your search" function accessible on the results page?
The idea is to give the user the possibility to predefine sets of sites to be excluded. The problem is that there are somtimes sites I especially don't want to find (like amazon, ebay and "price finder"-sites). So maybe a user should be able to define such sets and/or there could be predefined sets (like: no commercial/bussines/... sites).
I guess this depends on the way it could be realized. The easiest way might be to just add the possibility for the user to always exclude certain domains - or other filters like "no forums", "no newsgroups" as well - in the preferences and save them as a set. The user should than be able to enable or disable this set by default in the preferences and "on the fly" in the "refine your search"-box. Maybe a second box like "My custom refinements" would be useful.
The real advantage would be, that a user could get a better recall+precision based on the (average) aim of his search, which (I think I'm not the only one) is often just "useful and directly available information" above meta information (like books, other products etc.).
