This evening, we rolled out an industry leading blog search engine for Bloglines. In addition, there’s a new ‘Blogs & Feeds’ tab on the main Ask site. We started working on the new search engine soon after Bloglines was acquired by Ask last year, and the engine is the result of a lot of hard work by both the Ask search team in New Jersey and the Bloglines team in California. Generating an index with over 1.5 billion archived blog posts, and keeping it updated with new blog posts (within 5 minutes of us receiving the posts) is non-trivial. Please check it out, it’s quite an impressive piece of work.
