what is the Mongoose find query using nodejs?
<p>This is my players model</p>

<pre><code>var mongoose = require('mongoose'),Schema = mongoose.Schema;  
var playerSchema = Schema({  
  name: String,
  password: String,
  country: String
});
mongoose.model('players', playerSchema);
</code></pre>

<p>This is my countries model</p>

<pre><code>var mongoose = require('mongoose'),Schema = mongoose.Schema;  
var countrySchema = Schema({  
  name: String,
  isActive: Boolean
});
mongoose.model('countries', countrySchema);
</code></pre>

<p>And this is app.js </p>

<pre><code>mongoose.model('players').find({}, function (err, players) {
            console.log(players);
              if (err) {
                  return console.error(err);
              } else {
                  res.format({
                      html: function(){
                        res.render('players/index', {
                              title: 'Players List',
                              "players" : players
                          });
                    },
                    json: function(){
                        res.json(players);
                    }
                });
              }
        });
</code></pre>

<p>In players model I have countryId and in countries model I have corresponding countryName. Now I want to find players with country name with same find() query.</p>
