No :-). For what its worth, Google never worked that way either, it used Page Rank initially to sort results by social importance. I would guess that the last keyword based engine of any merit was AltaVista. AV had the issue of returning all pages with your words but it had no notion of sorting them (at least initially, you can read their patent as well)

These days its fairly easy to code up an n-gram index and host it on a moderate server. If you have a corpus of documents you can see how well it works. The simplest corpus is to just down load all of Wikipedia. Last time I checked it fit on a 2 TB disk drive.

You could also use the Common Crawl database and index it as you would like, or talk to the Internet Archive project for some sort of collaborative project. However I will warn you that of the people who have done this experiment (and it was a new hire task at both Blekko and Google where I worked) folks quickly discovered it wasn't very useful.
