Yahoo Buzz Top Searches - Where's Historical Data?

[techbuzz]

Where can I find daily historical data for the Yahoo Buzz top daily searches? I can see todays info and, had I already signed up for the RSS feed I suppose I could go back, but at the moment all I can find is today's data and the rss feed is only displaying today's data. Know a site that is logging this so I can go back day by day and see what the top searches were?

Current top searches can be seen here: http://buzzlog.buzz.yahoo.com/overall/

I think a search phrase for one of my sites ended up on the top searches or movers list on Yahoo Buzz this weekend, generating 18k+ visitors from Yahoo search. Thanks.

I do not think any such tool is available.
