But I'm not too sure I like it.. it tends to generate extra clutter. ::sigh::
However, this is cool. As you search, google shows you the number of results, and searches based on the stuff you've typed in so far.
All of this and more, from Google Labs: http://labs.google.com/
There's also a web accelerator that I can't use... http://webaccelerator.google.com/
A9.com, on the other hand is also pretty spiffy. I like their searching category choices. And searching there gives me a π/2% discount at Amazon, which is nice too (yay, I can save ≈1.57%) And they have pretty good search results... similar enough to google. Or perhaps a9 uses google? o.O
