It was only a matter of time.
Google has been promising blog search for a couple of years. Finally, this morning they rolled out a blog search engine capability. Not surprisingly, it’s labeled “beta.”
According to a Google, “The goal of Blog Search is to include every blog that publishes a site feed (either RSS or Atom).” It looks for sites that update pinging services and crawls in real-time. It will “only include items that have been posted since it started indexing a given blog. For most blogs, that will be around June 2005.” Note that it is not a full-text search engine across all sources. It doesn’t access and index the full content available on the publisher’s server (you can find out more about how Google Blog Search works at http://www.google.com/help/about_blogsearch.html).
