How can I find out if a site listed within Yahoo search results is coming from Inktomi?

The only other source that comes to mind about Inktomi is http://search.positiontech.com, at times the results are not always identical, but usually they are pretty close. But I'm not entirely sure if this would now be pure inktomi results as it use to be. I would assume by now they would of possibly combined yahoo's crawler findings with the old inktomi by now.

The ones that are paid search are clearly indicated, but all the sites in the regular listings are Yahoo! Search. It isn't Inktomi; Yahoo acquired Ink and now uses their own search technology.

Their own search technology based in part on Inktomi database, right? These appear among the search results.

Which is what I was getting at. Looking at which among the results were Inktomi, and which are being pulled another way, and those which may have Inktomi in common with other factors.
