Google has revved up it’s blog search engine with the addition of date restrictors. Go to the Advanced Blog Search page to search posts written within a specific date range.
While Google blog search is still my most often used blog search tool, I agree with ResearchBuzz that it could benefit from some of the advances features available in regular Google. I’d like to be able to search blogs within (or excluding) a particular domain or subdomain.
