We have seen lots of innovative services from Google Labs. Yahoo! does have similar lab too, called Yahoo! Research Lab.

Recently, Yahoo! offering is a test version of Yahoo! Mindset.

Yahoo! Mindset allows you to sort search results for your query into commercial or non-commercial (informational) results, based on whether you’re shopping or seeking information. Commercial implies that the primary purpose of a given page is to sell you something. Whereas, informational implies that the primary purpose of the page is to provide information related to your search.

There is a slider bar is the search page, which allows you to move it to the right for commercial results and to the left for non-commercial results. The result will change immediately while you are sliding the bar.

Really hope to see the searching results can be tweaked to suit different goals in real action soon. With these tweaks we can get specific searching result rather than meaningless ads in our search. :)
