Sometimes (or almost always) when I look up something I like to read the Wikipedia article about it, then if it's a movie, for example, IMDb, or WebMD if it's a medicine related thing and so on, you get the idea

Is it possible to make it happen, to set a list of "preferred sites" to show results from first, so that you don't need to use the !bang syntax if you search and don't find it in the results (or in the very first)?

e.g. search for "monopoly" and you get the game's related results first... then a bunch of results down you find the Wiki article. I want to see the Wiki result first, and to be able, for example, to hide anything from Facebook (just an example)
