We’re used to search engines matching the keywords we query, returning pages that contain those words.
But what if search engines worked differently?
It seems like search engines are starting to do that, with more direct answers to searches that show up as a fact, appearing at the top of a set of search results in an “answer box”. And those questions are sometimes something more than just “what’s the weather like in Warrenton, Virginia?”
Instead of indexing pages on the web, and what those pages contain, search engines can be used to search other data sources, such as a data graph. Or knowledge bases at Google, through Google’s Knowledge Graph.
