"Google seems to have released a new button found at the bottom of the SERPs page.  The new button is to the right of the normal \"search\" button but says \"search harder\".  I have not seen this myself, it might be one of those things Google is rolling out to some people.  A thread at WebmasterWorld has several people who have seen this.Basically, if you do a search on a very general keyword, such as cars.  It asks you if you want to \"search harder\", if you click that search harder button, it takes you to a different SERPs page for cars found here.  When you click on the link, see the URL: http://www.google.com/search?q=cars&amp;btnmeta%3Dtha%3D1%26seen%3D7d8882011a9da6f0%2CpaQUq1\nBgsA8J%2CRVuszxD0ZLYJ%2CKWbRZb06QI8J%2CRsWGZdkk_oUJ%2CEItB\n6rHmy6YJ%2C4DBTRhlVuqUJ%2C8pAZTckoaBMJ%2CDk2ynlAPOA0J%2C8uB\nJ_n5AyTYJ%2CXY7ep7ykeoAJ%2C=Search+HarderVery interesting...As more information comes my way, I will post it."^^<http://www.w3.org/2001/XMLSchema#string>
