Yahoo Inc has introduced a software development tool that lets outside parties create customized views of Yahoo Web search results, the company said on Thursday.

Making good on one piece of a strategy to open up its core network services, Yahoo said it was offering SearchMonkey, a technology that lets website owners display selected Yahoo search results on their sites.

Instead of offering a one-size-fits-all approach to search, Yahoo is allowing website owners and users to have more choice about what information they want to show and see when they use Yahoo search.
