Google has launched Google Blog Search in beta version. It allows to
search into blog notes from bloggers around the world. Unlike
Technorati, a blogger do not have to ping (notify) his post with Google
Blog Search. The blog notes are retrieved from RSS feeds registered
only once thru Google Sitemaps.

I've just tried this and OMG i cannot wait for it to become public to the average user. Great job google.
