Google is stupid. I mean, as in, Google is a blithering idiot that got dropped on it's head as baby, repeatedly, and when that didn't work, mom bashed it on the head with a two by four and when it survived that, mom gave up. It's search filters do not search based on the relevancy of what you typed, but based on popularity, which 70 percent of the time results in almost all of your hits being completely unrelated to what you asked for, in spite of how fucking specific you were. Bing has much better filters.
