Google's Search Appliance has reached a new version (5).

Here's the press release: google.com/intl/en/press/press ...

Interestingly included in the press release (which really deserved a press release of its own):

"In addition, Google also announced Google Enterprise Labs, a site dedicated to improving the search experience inside businesses by providing early access to such search innovations..."

I'm guessing these search innovations, if popular, will make it to Google.com is due course.
