You can just loop over your array:

var doc = { /* your json */ };

function getById(arr, id) {
    for (var d = 0, len = arr.length; d < len; d += 1) {
        if (arr[d].id === id) {
            return arr[d];
        }
    }
}

var doc_id_2 = getById(doc.results, 2);

If you don't want to write this messy loops, you can consider using underscore.js or Lo-Dash (example in the latter):

var doc_id_2 = _.filter(doc.results, {id: 2})[0]
