Finally! Google has now joined the ranks of daypop, Feedster, IceRocket and Technorati in searching the blogs. Yes, it's still beta and can be accessed either at http://blogsearch.google.com or at http://www.google.com/blogsearch. It does a very good job, I must add.
You can sort by date or relevance (default) and it will also give you the 'related' blogs too. Nice!
