When you search on Yahoo!, our search engine instantly searches and sorts billions of web documents, makes a decision on each one's comparative relevancy to your search query, and offers these web pages as ranked results. Search engines don't have the ability to ask questions, so they rely on the search terms you enter to interpret and determine the intent of your search.

Yahoo! Search ranks results according to their relevance to a particular query by analyzing the web page text, title and description accuracy as well as its source, associated links, and other unique document characteristics.
