  var fi = fluidinfo({username: "username", password: "password"});
  var onSuccess = function(result) {
    // A callback to do something with the result
  };
  var onError = function(result) {
    // A callback to handle when things go wrong
  };
  fi.query({select: ["fluiddb/about", "ntoll/rating", "terrycojones/comment"],
    where: 'oreilly.com/title matches "Javascript"', onSuccess: onSuccess, onError: onError});
