Which direction would your clever robot look?
site logs >> IP of recent user >> visit user's computer >> study cookies belonging to target site >> retro-convert to plain-english terms
site database >> customer records >> information on recently purchased items >> retro-convert to plain-english terms
plant onsite observer* >> note arrival of each visitor >> check visitor's cookies while they are logged on
Barring a few trifling obstacles involving passwords and encryption, it could be done. Though somehow I'd associate it more with a talented 14-year-old than with an established search engine. The SE has more to lose if it comes out.
* Or encourage site to do it for you, in the form of voluntarily installed Analytics. That approach seems vastly easier. You wouldn't need to mess with cookies; just keep track of the visitor's activities on Checkout page.
