as powerful as they are, search engines have huge weaknesses. For example, a recent Google search on the word Linux took just 0.4 seconds, but it had 95 million hits. Too bad if the one you need is No. 10,000 on the list.
But researchers are poised to revolutionize search technology over the next few years. The most common thrust is to personalize search engines so that they know, for example, that if you’re an IT professional and you search for mouse, you’re more likely to want information about PC devices than about animals.
