Specifying Mongo Query Parameters From Client Controller (MEAN.JS)

Another way is to just pass the search parameters in the query method, like this:

 $scope.searchart = function() {    Articles.query({start:$scope.startDate, end:$scope.endDate}, function(articles) {        $scope.articles = articles;    });};

and then at the server side controller, read your query string parameters like this:

exports.searcharticle = function(req, res) {    Article.find().where('date').gt(req.query['start']).lt(req.query['end']).exec(function(err, articles) {        if (err) {            res.render('error', {                status: 500            });        } else {            res.jsonp(articles);        }    });};

This way doesn't require more routes or services.

It's probably not the cleanest way, but you can create a new service (or edit the current one to work with several parameters):

.factory('ArticlesService2', ['$resource',    function($resource) {        return $resource('articles/:param1/:param2', {            param1: '',            param2: ''        }, {            update: {                method: 'PUT'            }        });    }]);

Then call it in your controller :

$scope.findWithParams = function() {    $scope.article = ArticlesService2.query({        param1: $scope.aYearFromNow,        param2: $scope.aMonthAgo    });};

On the back-end, you'll need to prepare a route :

app.route('/articles/:param1/:param2')    .get(articles.listWithParams)

Add a function to your back-end controller :

exports.listWithParams = function(req, res) {    Article.find()    .where('date')    .lt(req.params.param1)    .gt(req.params.param2)    .sort('-created').populate('user', 'displayName')    .exec(function(err, articles) {        if (err) {            return res.send(400, {                message: getErrorMessage(err)            });        } else {            res.jsonp(articles);        }    });};

Should work, haven't tested it though.
