Yahoo! Search Technology (YST) works night and day, scouring billions of documents on the Internet, to give you the most comprehensive, up to date, and relevant search experience.

Yahoo! Search provides quick, intuitive access to the wide variety of information available on the Web. Each time you search, Yahoo! Search Technology instantly scans through its comprehensive database of web pages, determines which pages are relevant to your search query, and then returns a ranked list of these web pages on the Yahoo! Search results page.

YST ranks web pages according to their relevance to a particular query by analyzing document features such as text, title and description accuracy, source, associated links, and other unique document characteristics. A single Yahoo! Search returns immediate results from a database that is updated daily to incorporate newly created and changing pages, late-breaking news, and other time sensitive information.
