Because of the human involvement the database is rather smaller than the typical search engine database, and it is more focused. Many also feature a search program, but it is the directory's subject categories that are searched, not a much larger, uncategorized database as is the case with search engines. Algorithms and search protocols vary from search engine to search engine, and so results vary also. Also, since words are often used figuratively, their literal meanings in a document are not an infallible indicator of content. Consequently, some search results can be skewed and unrelated to the search terms input to the search engine.
