extracting values from json using Underscorejs

I have a json from which I need to filter the objects whose name value matches the passed input and then pluck the href value from the corresponding links object having the ref value of self. I am attaching the code snippet as well as my approach of filtering. I am using Underscore.js.

var jsonObj = [
{
  "links": [
    {
      "rel": "self",
      "href": "http://hostname:port/state/644444",
      "variables": [],
      "variableNames": [],
      "templated": false
    },
    {
      "rel": "city",
      "href": "http://hostname:port/city/6184",
      "variables": [],
      "variableNames": [],
      "templated": false
    }
  ],
  "stateId": 65986,
  "countyId": 6184,
  "name": "AAATest",
  "population": 20000,
  "location": "SFS CSR"
},
{
  "links": [
    {
      "rel": "self",
      "href": "http://hostname:port/state/65987",
      "variables": [],
      "variableNames": [],
      "templated": false
    },
    {
      "rel": "city",
      "href": "http://hostname:port/city/6184",
      "variables": [],
      "variableNames": [],
      "templated": false
    }
  ],
  "stateId": 65987,
  "countyId": 6184,
  "name": "2k8std511",
  "population": 20000,
  "location": "SFS CSR"
  }
]

var keywords='2k8std511';

var filtered = _.filter(jsonObj, function (item) {
                return (_.contains('2k8std511', item['name']));
            });
console.log(_.chain(jsonObj)
 .pluck("links")
 .flatten()
 .value());

Please let me know how to filter based on the given keyword:

Example input: AAATest Expected output: [href:'http://hostname:port/state/644444']
