Y! BOSS Search

Hi Hannes & Philip, I have been researching Yahoo Boss, and it looks like there are a number of ways we could improve on the existing search (I'm not referring to the autocomplete search, but rather the full-page search). I found an interesting article on Tech Crunch about how they implemented Yahoo Boss: http://www.techcrunch.com/2008/11/26/techcrunchs-new-search-engine-powered-by-yahoo-boss/ One of the key things that they do is manually feed data to Yahoo via XML. This allows them to associate arbitrary metadata with each page. That way they can offer advance search options like search by author or category. Are we feeding any additional data to Yahoo, or just rely on them to crawl the sites? If it's the latter, would we want to start manually feeding data doing to provide better search options? How would that work with our infrastructure? Thanks, Stew
