Just tried a few search terms, and very surprising results. Lot better than the preview version i tried a few months ago.
Still seems to rely on exact phrase in titles and on page, and less weight to incoming links(compared to google). No result for the term i just tried looks out of place, unless you are used to seeing google results.
Oh shucks, I was just going to do a bit of checking this out this morning and read this message in 10 different languages:

Yep it's down. I was going to check some things too. If my logs are correct, one of my sites should be represented in there with roughly 400% of it's 1000 pages or so included in the index....
