Google has a very cool new beta project, it is called Google Suggest. It works just like Google's "Did you Mean?", except it works as you type instead of after you send the request. One of the neat features of it is that it tells how many results you can expect for each query. This can help you fine tune your search, and see what words would work well in a query. It is still in beta, and apparently crashes Konqueror, Firefox works fine.
