Facebook API Search Types

We support search for the following types of objects:

• All public posts: https://graph.facebook.com/search?q=watermelon&type=post
  This search type does not support limit/offset paging. 
• People: https://graph.facebook.com/search?q=mark&type=user
• Pages: https://graph.facebook.com/search?q=platform&type=page
• Events: https://graph.facebook.com/search?q=conference&type=event
• Groups: https://graph.facebook.com/search?q=programming&type=group
• Places: https://graph.facebook.com/search?q=coffee&type=place.
  You can narrow your search to a specific location and distance by adding the center parameter (with latitude and longitude) and an optional distance parameter:
  https://graph.facebook.com/search?q=coffee&type=place&center=37.76,-122.427&distance=1000
• Checkins: https://graph.facebook.com/search?type=checkin (This request returns you or your friend's latest checkins, or checkins where you or your friends have been tagged; currently, it does not accept a q= parameter.)
• Objects with location. The following will return information about objects that have location information attached. In addition, the returned objects will be those in which you or your friend have been tagged, or those objects that were created by you or your friends. There are important behavioral differences in the results depending on the permissions your app has acquired. Please see the documentation for the location_post FQL table for more information.
  • To search for objects near a geographical location, use type=location and add the center and distanceparameters: https://graph.facebook.com/search?type=location&center=37.76,-122.427&distance=1000
  • To search for objects at a particular place, use type=location and specify the ID of the place. For example for Posts at Facebook HQ, use: https://graph.facebook.com/search?type=location&place=166793820034304
