title: How to filter Azure logs, or WCF Data Services filters for Dummies
body: <p>I am looking at my Azure logs in the WADLogsTable and would like to filter the results, but I'm clueless as to how to do so.  There is a textbox that says:</p>
  
  <blockquote>
    <p>"Enter a WCF Data Services filter to limit the entities returned"</p>
  </blockquote>
  
  <p>What is the syntax of a "WCF Data Services filter"?  The following gives me an InvalidValueType error saying "The value specified is invalid.":</p>
  
  <pre><code>Timestamp gt '2011-04-20T00:00'
  </code></pre>
  
  <p>Am I even close?  Is there a handy syntax reference somewhere?</p>
