Regex matching one word but not matching another

Question

What is wrong in this fiddle.

http://jsfiddle.net/RPdx4/

 function getMatches(data,city){
             var matchArr = [];
             var pattern = new RegExp("\\b("+ city +")","gi");
        for (var i in data){        
                 var searchStr = data[i].searchstr;
                 if(pattern.test(searchStr)){
                    matchArr.push(data[i]);
                }
            }
            return matchArr;
        }

I am able to match the first address object and and the last address object but i am not able to match the second one.But the second one also has the same word. Any idea why?

Just use .indexOf()

 function getMatches(data,city){
        var matchArr = [];
        for (var i in data){        
                 var searchStr = data[i].searchstr;
                 var index = searchStr.indexOf(city);
                if(index!==-1) {
                    matchArr.push(data[i]);
                }
            }
            return matchArr;
        }

var arr = getMatches(x,'Dar es');
alert("arr: " + arr.length);

OK, Regex just

var pattern = RegExp('\\\\b' + city + '\\\\b')

or

var pattern = RegExp("\\\\b("+ city +")")
