InsideFacebook shares that Facebook Graph Search addresses several categories of search — some that were made explicit during Facebook’s announcement on Tuesday and others that are still being discovered as beta users try it out.
Facebook’s combination of identity and structured data allow users to answer very specific questions that no other service can. Although Graph Search uses natural language processing to understand what users are actually looking for rather than simply matching keywords, one might get a better sense of what’s possible with the tool by thinking about the following formula:
Type of Content + Subject + Type of Person + Location + Time
Users can combine any of those options in a query.
