We should have seen this coming after Technorati brought in their Blog Search feature. Now Google has “Blog Search” tool for the blogger.com blogs, without the pain of tagging your blog. As always, you can notice the detail to which they go. The “search options” lets you search a particular blog (or multiple blogs), even a blog post using its permalink or within a date range. The Advanced search option gives you whatever you can ask for; search for posts in a particular language, by an author, safe search and so on.

Brilliant work, that would certainly delight the blogger.com users around the world!

Update: I learnt that the search works of all blogs that have a feed and not just blogger.com blogs.
