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 the comparative relevancy to your search query, and offers these web pages as ranked results.

YST ranks web pages according to their relevance to a particular query by analyzing document features, including text, title and description accuracy, source, associated links, and other unique document characteristics. A single search gives you immediate results from a database that is updated daily to capture newly created and changing pages, including late-breaking news and timely events.
