Search engines give their users an almost-magical way to go from their goals to the information that meets those goals. When the items retrieved match the user’s intent, then we say that they are relevant for that user and that query. “Relevance” spans much more than just the function used to rank the search results. Retrieving relevant results includes the presence of the data in the catalog, the way the data is analyzed, the methods used to augment and send the user’s query, going beyond text to vector representation, feeding back user behavior, and of course, the ranking function.
