Yahoo (NSDQ: YHOO) has added both Yahoo Answers and Wikipedia to Yahoo oneSearch, adding community-based information to its service. The Wikipedia page is broken into digestible bits for the mobile screen. Yahoo has also rolled out flight information search, so if someone searches for a particular flight they can get flight status, times, gates and so on. There are more details on this coming later…

Update: While some speculate on whether Yahoo would do best to break up into advertising, search and subscription businesses, following advice in an analyst note released today, the company released further details on its new iteration of oneSearch, which integrates its assets even more than before. From the Yahoo Search Blog: The service is being rolled out within Yahoo mobile portals across 18 markets—Argentina, Australia, Brazil, Canada, France, Germany, India, Indonesia, Italy, Malaysia, Mexico, the Philippines, Singapore, Spain, Thailand, the United Kingdom, the United States, and Vietnam. The integrated search will incorporate Yahoo Answers and Wikipedia results with its existing search categories of the main Web (text and image), the mobile Web (text only), Flickr, news and business listings. “Ultimately, oneSearch’s goal is to get you instant answers from a variety of sources and Yahoo! properties so you have the right information when you’re mobile,” writes Paul Yiu of oneSearch on the blog. But given the size of a mobile screen, will users be happy extending that list of results even more?
