title: Meteor.call checking array parameter
body: <p>I am doing a <code>Meteor.call('searchDatabase', keys...)</code> that is executed whenever a user submits a search. I am currently passing an array of the words submitted called <code>keys</code>. However, I do not know how to do the necessary <code>check(keys, ?)</code> on the server side. I originally thought that I could do <code>keys.forEach(function(element) { check(element, String)}</code>, but i still get a <code>Did not check() all arguments</code> error. Should i just pass the submitted search as its original string in the Meteor method call and then break it up on the server? or is there a way to check that keys is an array?</p>
