a.k.a. run-time business intelligence
When used in computer searching, "relevancy" measures how closely a document or Web page matches the users' search query. Many search engines return the search results in a hierarchy from the most relevant to the least relevant. Search engines rank the relevancy of Web pages using several factors including the more often a term appears in a document, the more relevant it is, and the number of clicks on an item makes it more relevant (also known as run-time business intelligence).
