Google launches a blog-specific search
http://www.google.com/help/about_blogsearch.html
It searches your feed only. Which means: 1) no posts older than July 2005 (so far) and 2) if you only publish a summary in your feed, that's all Google has to search on. Yet another reason to put full posts into your feed.
