Google has launched Google Blog Search.

The new beta search service lets users search for blogs and posts that match their interests, and is based on the same technology that powers Google's Web search.

The new feature is also integrated with Google's Blogger service.

"The ability to search over blog content has been one of the most highly requested features from our users", the company said.

Google Blog Search will automatically check blogs that syndicate posts using RSS or Atom, updating the search index when new posts are found.

Search results reveal blogs relevant to a search term, and also individual but relevant posts on unrelated blogs reflecting the term,

The new beta service is currently available in English, French, Italian, German, Spanish, Dutch, Russian, Brazilian Portuguese, and Korean, with additional languages to follow.
