I don't seem to have this issue on any other webshop that uses normal keyword searches and always wondered what Amazon did to mess it up so much and why people use that website (also for other reasons, but search is definitely one of them: no way to search properly). The answer isn't always "massive resources" towards being more hi-tech

But, thanks, this explains a lot about Amazon's search results and might help me steer it if I need to use it in the future :)
