Sorting data AngularJS / NodeJS / MongoDB

Question

I have more than 25000 data in a collection so I have to optimize for the front-end.

First with node JS, I did a pagination for the rest API:

 app.get('/api', function(req, res, next) {

  Image.paginate({}, req.query.page, req.query.limit, function(err, pageCount, articles, itemCount) {

    if (err) return next(err)

    res.format({
      html: function() {
        res.status('articles').send({
          articles: articles,
          pageCount: pageCount,
          itemCount: itemCount
        })
      }
    })
  })
});app.listen(3000);

So i can access my data with:

localhost:3000/page=1&limit=5
localhost:3000/page=2&limit=5

...

But I would like to be able to search by id in all the JSON I have:

localhost:3000/id=[search by id]

because, in my JSON I have for each data:

"_id":"542e65368a1cec1227ae2bac",
"_id":"542e66b78a1cec1643e0f032",
...

How I can to do that?

Thanks for your help!
