Instant Search by Yahoo!
Posted September 15th, 2005 by Max Chirkov
Yahoo! just made available new tool - Instant Search Beta. Instant search is pretty much the same search, the only difference - it gives you straight answer while you're typing. For example type in GOOG and it gives your a blurb with Financial Information on Google with quotes and a chart. The same way you can enter your city weather or any other search query.
