Update search_test.js

THIS IS NOT CORRECT IMPLEMENTATION - the search functionality works, but will not post the information to the site.

Previously, we had: 

app.get('/the_menu', function(req, res){
    Menu.findOne(function(err, menu){
        res.contentType('json');
        res.send(menu);
        console.dir(menu);
    });
});

Problem: res and req are only available within their own functions. By putting them in the findOne function callback, nodejs had no idea what res and req were. 

Problem with current implementation: no way to send menu items to the specified page. I've posted the various attempts I've made and the problems I've had with each.
