Also for doing user searches in social websites, I don't get the results I am looking for:

Eg for query "Barack Obama" from Facebook graph api: I get :

{

  "data": [

    {

      "name": "Chi Linh Bui",
      "id": "248865755297304"
    },
    {
      "name": "Barack Obamanana",
      "id": "318956448258150"
    },
    {
      "name": "Barack Obamalad",
      "id": "1378793772451152"
    },
