Is it possible to retrieve a record from parse.com without knowing the objectId

Question

See the sample code below - in this case, the objectId for the record I am trying to retrieve is known.

My question is, if I don't know the Parse.com objectId, how would I implement the code below?

var Artwork = Parse.Object.extend("Artwork");
var query = new Parse.Query(Artwork);
query.get(objectId, {
  success: function(artwork) {
    // The object was retrieved successfully.
    // do something with it
  },
  error: function(object, error) {
    // The object was not retrieved successfully.
    // warn the user
  }
});

Query.get() is used when you already know the Parse object id. Otherwise, one can use query.find() to get objects based on the query parameters.
