Angularjs filter ng-repeat object

Here’s an implementation of full text search on a list of records.
You specify the fields you want search on;

HTML:

<input type="text" ng-model="toggleSearch"/>
<div ng-repeat="oneResult in filterResult = (result | lookupfilter:toggleSearch)"></div>

Angular:

function lookupFilter(){
    return function(items, searchText){
        var fields = [
        'field1',
        'field2',
        'field3'
        ];
        var length = fields.length;
        var regObj = new RegExp(searchText, 'gi');
        if (searchText.length > 2){
          return items;
        }
        var found  = items.filter(function(oneItem){
            for(var i = 0; i < length; i++ ){
                if (oneItem[fields[i]] != undefined &&
                    oneItem[fields[i]].match(regObj)){
                    return true;
                }
            }
            return false;
        });
        return found;
    };
}
angular.module('home', [])
.filter('lookupfilter', lookupFilter)
