Ajax search implementation about node-express-mongoose-demo

[madhums]

yeah its quite simple I guess.

1. Create an endpoint which sends the typed letters

     /* file: config/routes.js */
   
     var search = require('/path/to/search.js')
   
     app.get('/search/:term', search.results)
   
     app.param('term', function (req, res, next, term) {
       req.term = term
       next()
     })

2. Perform the query and send the results in json format

     /* file: app/controllers/search.js */
   
     var mongoose = require('mongoose')
     var Article = mongoose.model('Article')
   
     exports.results = function (req, res) {
       Article.
         .find({ title: req.term })
         .populate('user', 'name')
         .exec(function (err, articles) {
           if (err) return next(err)
           if (!articles) return res.json({ error: 'No articles found for query '+ req.term })
           res.json(articles)
         })
     }
