Using a search engine to find information related to a topic by entering keywords or phrases. The search engine ranks returned pages, articles, and other content by relevance, content quality, and site authority, letting users discover knowledge entities that were not explicitly linked to their starting point. Advanced search features, such as filtering by date or restricting the search to a specific site, help narrow results further. As a solution to disconnected knowledge entities, this method relies on the searcher's own query formulation rather than on links, indexes, or citations built into the content itself.
