It's been about a month since Yahoo! Search BOSS launched, so it seems like an opportune time to look at some of the mashups and search products that have been built using the BOSS APIs & services. As we've said before, our goal with BOSS is to remove as many of the barriers as possible to creating new search products. By providing deep access to Yahoo! Search's investment in engineering, sciences and core search infrastructure and removing key usage restrictions, we are encouraging a whole new level of innovation in search experiences. We are very excited to see the diversity in products that many of you have already created. What follows is just a small sample of what's being built -- we'll post again soon with a bunch more.

4HourSearch -- Built by Sam Pullara, 4HourSearch is a demonstration of the power of Yahoo! Search BOSS combined with a slick user interface. Aptly named, it took Sam four hours to build the site using a combination of the BOSS API and YUI design tools.

PlayerSearch -- Ted Kasten and team are building a sports search engine that pulls in content from a host of sources, including BOSS. Fantasy sports fanatics, check it out here.

NewsLine -- As part of the Daylife Developer Challenge, the folks from Dipity built a mashup using their timeline API, Daylife's news API and the BOSS API. The result is a really interesting way to visualize news for any topic. Congrats to the Dipity team on winning the BOSS mashup prize!

Tianamo -- Tianamo is a 3D search visualization early prototype built by Lachlan James. It maps the relationships between the search results from the BOSS API and displays them visually. To check it out, you'll need to be running Windows with Java 1.6+.

As you can see, the possibilities for creativity and innovation in search are almost endless. If you're building a mashup or product using BOSS, make sure to tag it with "bossmashup" on Delicious so we and the rest of the world can discover it.
