You may use the following code:

var stringTosearch ="test ,string, test"; //true
var stringTosearch ="test string test"; //true
var stringTosearch ="test stringtest"; //false
var stringTosearch ="teststring test"; //false

if (new RegExp("\\b"+"string"+"\\b").test(stringTosearch)) {
  console.log('string found');
  return true;
} else {
  return false;
}
