title: Complexe RESTful GET queries
body: <p>I understand how to do queries like GET <a href="http://localhost:8080/rest_mysql/books/1" rel="nofollow">http://localhost:8080/rest_mysql/books/1</a> and pull with an ID, in this case "1", but lets say you wanted to search for a book with 2 variablies instead of 1. Can this still be done via GET?</p>
