AccountModel.find({ age: { $gt: 18, $lt: 30 } }, function(err, accounts) {

console.log(accounts.length); // => 2

console.log(accounts[0].username); // => randomUser1

mongoose.connection.close();

});

Here, we use the standard MongoDB commands $gt and $lt for the value of age when passing in our query parameter to find documents (that is, find any document where the age is above 18 and below 30). The callback function that executes after find references an accounts array, which is a collection of AccountModel objects returned from the query to MongoDB. As a general means of good housekeeping, we close the connection to the MongoDB server after we are finished.
