Amazon RAID Search – Odd Results

Does Amazon know what I am looking for more than the search phrase that I just typed in? Perhaps… but perhaps not so much. I was recently searching around Amazon for a few separate classes of items. The first thing I searched for was headphones and headsets with microphones. Following that I decided to turn my attention to the costs of RAID Arrays to see if there were any reasonably priced options for a home user. To my surprise the first page of results contained not hard drives, raid arrays or anything similar but headphones and headsets. Hmm. Yes, I did look for that to begin with but now I am searching for something else! Anyway, I though it was funny so here is a screen shot.
