Yes, it finds the thing which represents John Smith. From that thing, remaining data can be retrieved. Below is simplified psuedo code to find him and print his SSN:

   pT = X("(person) 'john smith'");
   pSSN = T_Val_get(pT, pSSN_Cls);
   str = T_Name(pSSN);
   print(str);

Some functions (ie X, T_Val_get) can return 0 to many things thus the following programming structure is typical:

  while (pT = X("(person) 'john smith'")){     // Process current person
