Today google announced a new feature in Google Blog Search which lets us search articles by date ie Last Day, Past Week etc. You can also choose start and end dated yourself.
They have also incorporated some improvements in search quality that should make your blog-search experience even better.
Google Blog says:
“Ever since Google Blog Search launched, we’ve noticed that the universe of blogs has truly exploded–our index is doubling every six months. Perhaps even more striking, though, is that there’s no one region in the world that leads the growth of blogs. Self-publishing clearly has global appeal, and blogging makes it easy for everyone on the web to share their voices and connect. True, there continues to be blog spam (and we continue to fight it), but our blog search reveals the great range and quality of ideas and writing out there”
