Will BOSS save Yahoo's dwindling search market share?

Yahoo announces the launch of BOSS: Build Your Own Search Service. Using BOSS, developers and web service providers can use the Yahoo search engine and build applications on top of it. The move to open up Yahoo's search code seems to be aimed at increasing the reach of Yahoo search, so far a distant second to Google's web search, that currently dominates most of the search and online advertising industry. But will outside developers be able to save Yahoo?

Here's what Yahoo has to say about BOSS:

"BOSS (Build your Own Search Service) is Yahoo!'s open search web services platform. The goal of BOSS is simple: to foster innovation in the search industry. Developers, start-ups, and large Internet companies can use BOSS to build and launch web-scale search products that utilize the entire Yahoo! Search index. BOSS gives you access to Yahoo!'s investments in crawling and indexing, ranking and relevancy algorithms, and powerful infrastructure."
