How To Search Facebook?

How does Facebook search work?

• More specifically, what factors determine the priorities they assign in response to a given query? I'm looking for answers that address numerous scenarios including queries that... Specify the "type" of result (objects such as users, posts, pages, etc. or connections like friendships, likes, tags, etc.), Have https://developers.facebook.com/docs/reference/api/#auth as well as ones that don't. Have conditionals such as "since" and "until." Don't even specify a type, such as this search for the word https://graph.facebook.com/search?q=QUERY.

  I am actually working on an app that uses /search to search places and I use a bit of all scenarios. I couldn't write down a specific order they appear in and to be honest I highly doubt it's something as easy. I'm 99% sure it works like the Search in Facebook does, using the user data to bring up the most relevant results. I live in Ireland for 2 years now, but while testing the app I constantly receive search results from Romania and actually close to my Hometown, which are relevant to me. Regarding your observations, Facebook's algorithms might take into account the source of the request as well - which would be good, means it only improves as your app gets more users.
