How to append query strings to the URL in Angular ui-router

Question

I am pretty new to AngularJS. I am using ui-router and node.js as my UI server for API calls to another server. Right now, I am having trouble appending query strings to the URL depending on user input (dropdown selections).

My AngularJS controller code:

$scope.getResults = function() {
    server.getResults($scope.myColor, $scope.mySize)
    .success(function(data) {
        results = data;
    });
};

AngularJS service for the above function:

app.factory('server', ['$http', function($http){
    return { 
        getResults : function(color, size) {
            var req = {};
            req.color = color;
            req.size = size;

            return $http({
                method: 'GET', 
                url: 'results',
                params : req
            });
        }
    }
}]);

ui-router in Angular:

$stateProvider.state('home', {
    url: '/home',
    templateUrl: '/home.html',
    controller: 'MainCtrl',
    data:{ 
       pageTitle: 'blah' 
    }
})

In Node.js, I have my route like this:

app.get("/results", function (req, res) {

    var api = 'some api call/' + req.query.color + '/' + req.query.size;

    request(api, function (error, response, api) {

        if (!error && response.statusCode == 200) {
            res.json({
                Color: req.query.color, 
                Size: req.query.size,
                Answer: api
            });
        }
    });
});

I want to have the browser url go from /home to /home?color=Red&&size=Large

Obviously I am not doing this right, the browser url is not dynamic right now. Please show how to do this correctly.

Do use reloadOnSearch: false options to stop reloading current route when changes occurs in state parameters.

$stateProvider.state('home', {
    url: '/home?color&size',
    templateUrl: '/home.html',
    controller: 'MainCtrl',
    data:{ 
       pageTitle: 'blah' 
    },
    reloadOnSearch: false //would not refresh state, for location changes.
})

Controller

$scope.getResults = function() {
    //change parameter of URL usingn $location.search.
    $location.search('color', $scope.myColor);
    $location.search('size', $scope.mySize);
    server.getResults($scope.myColor, $scope.mySize)
    .success(function(data) {
        results = data;
    });
};
