Developer Network initiative to provide an open search web services platform.
[5] The main goal and idea of BOSS was to give users, in its case developers, access to the Yahoo Search index for a small fee.
On August 17, 2010, Yahoo stated that BOSS would require some sort of ad or fee-based model to sustain itself.
The search experience was hosted by Yahoo and provided in an iframe which could be embedded on any web site.
According to a Yahoo press meeting in 2009, there were 30 million queries a day being run through BOSS powered web search pages.
