Blog Search, Included in Google History

Google Blog Search is now a part of your search history. That means every time you use the specialized search engine for blogs and you're logged in, your query is associated with your account and made available in the Google History interface. You can browse the list of queries and find a web page you visited in the past, but only if it was a Google search result. To augment Google History with all the web pages you visit, you need to install Google Toolbar and enable this option.
