Hi guys,
Did you try yahoo's instant search at http://instant.search.yahoo.com/
It gives you the result when you are typing your keywords only. Still in Beta phase , at the moment it gives a single result and only when you type the first keyword. For example, if you type Windows it displays Microsoft site but when you type Windows host it doesnt display anything. What do you feel about it?
