I do like the way they have different pages with different ways of looking at a query. They’ve got:
- Standard search, ordered by relevance over a recent period of time or by date
- Major blogs on the topic
- Related items on the query, like mainstream media news, photos, books and podcasts
The coolest thing has to be the custom range slider. When viewing results by relevance, you can choose a date range (so they are relevant, but not ancient), and you can choose predetermined ranges, or use a slider to make your own on the fly.
UPDATE: They have managed to get quite a bit of buzzzzz on the blogs about their launch. Check out their blogpulse.
(I found their announcement on reBlogger)
