	  List persons = new ArrayList();
		persons.add(new Person("Rafael", 21));
		persons.add(new Person("Suélen", 19));
		persons.add(new Person("Pedro", 23));
		persons.add(new Person("Rodrigo", 23));
	  Collection busca = (Collection) new Collect().in(persons).when("age").eql(23);//Compare with the field age is equals to 23, and return a new collection
	  Collection busca = (Collection) new Collect().in(persons).when().eql("23");//Compare the Person#toString() contais the string "23"
