Indeed, the first part (search that filters out site with ads, including affiliate links and the like) is something I wish for frequently. It isn't that I mind seeing ads (I can use AdBlock for that, and sometimes do), it's that I don't want to wade through spam sites when looking for info, and sites with ads seems like an obvious hard filter. Maybe DDG or the like could implement filter.
