Explain the searching process in a search engine with an example.
(96) 
VerifiedWhen a user enters a search term,the search engine uses an index to look up the term.If the term exists in the index,the search engine identifies all Web pages linked to the term.However,it needs some way of prioritizing Web pages based on how close each one is to the search term.For example,Emma makes picture-frame cookies and has a Web site for selling them.Someone searching on the term "picture frame" might see Emma's site listed,too.Because search engines are programmed to try to differentiate different types of search requests they can use other terms,such as "posters," "photos," and "images," to give a higher priority to Web pages containing these additional terms,along with the search term "picture frame," and a lower priority to Web pages containing terms such as "cookies" or "baked goods" along with "picture frame." Search engines vary in intelligence,which is why the user can use the same search term and get different results with two different search engines.
