Searching - and reSearching on the Web (beyond Google and Yahoo!)

It seems that many students do not know that there are alternatives to Google and Yahoo! While those search engines are very useful tools, there are hundreds of alternative search engines that enable us to look at the Web in a new way and enable us to extract information that we had not thought feasible previously. For example, we can search for spoken words in audio and in video files. We can view connections among Web pages in a graphical way. And, we can search the tail of the Web.
