Search Giant Google, Inc. has unveiled a new tool to search web journals or blogs. Google will index all blogs that publish feeds that automatically tell readers when they are updated. It will also gather data about blogs that tell other indexing sites about the entries they have made. According to indexing site Technorati there are more than 17 million weblogs which cover any and every subject reports BBC. As well as searching via the dedicated blog search page, Blogger users will be able to look up other blogs via a special box on the web-journal writing site.

Writing on his company blog Dave Sifry, founder and boss of Technorati, welcomed Google to the blogosphere and said the move was a "validation" of the blog writing phenomenon.

The new tool, unveiled Wednesday can be found at blogsearch.google.com

"There really has been a need for a world-class search product to expose this dynamic content to a worldwide audience," said Blogger founder Jason.

The appearance of the new Google tool, which catalogs the latest blog postings by looking at the Web feeds they generate, also makes it more likely that two other tech powerhouses and fierce rivals, Yahoo Inc. and Microsoft Corp., will develop a similar feature.
