Google Blog Search

For some time it was possible to force Google to access and search the Blogsearch database by manually formatting the URL in your browser's address bar.

Filtering spam was cited as a challenge for the technology, as there have been cases of spam posts appearing in the blogs and posts that the technology located and identified.

[6] In a review by Duncan Riley of the Blog Herald, the service was critiqued based on different criteria: search (which was given a "B"), numbers (which was given a "C−"), and size (which was given a "D").

He compared the usefulness of the technology to Technorati, except "with half as many results but without the error messages".

Access to Google blog search required the user be on a Google search page, then to click on "News" and then click the "Tools" button.
