```javascript

var Client = require('guava').Client,
People = Client.connect().collection('people');

People.on({ name: { $in: ['craig','tim','jake'], age: { $gt : 16 } } }, function(person)
{
	
	//craig is a 9001 year old male
	console.log('%s is a %d year old %s', person.name, person.gender, person.age);
});

```
