Regular Expression look for string and return everything between curly braces

I've been trying to use the approach suggested by another SO-User: https://stackoverflow.com/a/1820837/1324861

But without luck. Basically, I have a large JSON Object that I transformed into a string using JSON.stringify() in order to execute a regexp pattern against. My idea is to return everything between { } if my search term "soccer" is found anywhere between the curly braces.

My data could look like this:

{
  {
    User: "Peter",
    Hobbies: "Soccer, Football, ...",
    more...
  },
  {
    User: "Simon",
    Hobbies: "Pingpong, Soccer, Badminton",
    more...
  }
}

So if I searched for 'soccer' in my stringified JSON Object I'd like to get back the entire info on the user. How can I do this?

var json = [
  {
    User: "Peter",
    Hobbies: "Soccer, Football, ..."
  },
  {
    User: "Simon",
    Hobbies: "Pingpong, Badminton"
  }
];


var jsonString = JSON.stringify(json);
var regEx = /(\{.*?Soccer.*?\})/;
var user = jsonString.match(regEx)[1];
document.write(user);

You could inspire from this (without transforming your json into string):

var myData = [
  {
    User: "Peter",
    Hobbies: "Soccer, Football, ..."
  },
  {
    User: "Simon",
    Hobbies: "Pingpong, Soccer, Badminton"
  }
];
var results = "";
for (var i = 0; i < myData.length; i++) {
    if (myData[i]["Hobbies"].indexOf("Soccer") != -1) {
        results += JSON.stringify(myData [i]) + "\n";
    }                  
}
alert(results);

Something like "{[^}]*(S|s)occer[^}]*}"

Not that it doesn't make sense to stringify a JSON object to apply a regex on it (shudder) but hey, it's your CPU... You could use something like this:

\{[^{]+soccer[^}]+}

This should catch what you're looking for. But... Parsing JSON with regexes... Nononono...
