Yahoo! introduced new features of its search engine service, and’re intended to “make it easier and faster for you to explore the things that matter most to you,” said Larry Cornett. In additional to showing the familiar search results and ads, the new features include a left-hand panel that allows users to refine and filter their searches in various ways. Yahoo also unveiled long-expected features in its mail service, and new functionality, including video chat in Messenger, its instant messaging service. But they also said that once the deal’s consummated and Yahoo begins to use Microsoft’s Bing for the nuts and bolts of its search service, Yahoo would continue to offer a distinct look and feel to its search results. But the specific features offered by the two companies differ. Yahoo, for instance, has focused on offering follow-on searches on other sites in certain categories. A “how-to” query will offer users follow-on searches on eHow, wikiHow or YouTube, whereas “people” searches will offer follow-on searches on Facebook, LinkedIn and Twitter.
