[Developers] Freebase newbie: simple question

[Gordon Mackenzie]

You want Textual Comparisons? To match all states that contain the  
term "mass":



   {
     "country" : {
       "id" : "/en/united_states"
     },
     "filter1:name~=" : "*mass*",
     "iso_3166_2_code" : null,
     "name" : null,
     "type" : "/location/administrative_division"
   }
]


This is a great little primer for MQLing:
