Yahoo! adds new suggest search feature
The new search function is almost identical to Google's, with two exceptions. Google Suggest is only available through Google Labs, and Google Suggest shows you how many results are associated with each search term.
Google Blogoscoped also has a nice little chart showing the different suggestions Google and Yahoo! offered for identical search terms. Both services look pretty useful, but Yahoo! often wasted a little space by offering you the same word you'd already entered in the search box.
