title: Writing dynamoDB "OR" condition query?
body: <p>I want to query the dynamodb table with boolean or condition like SQL
  e.g. <code>Get me all the items where attribute1 = "no" or attribute2="no"</code></p>
  
  <p>I tried with <code>scanRequest.withScanFilter</code> but all the conditions are performed by doing boolean ANDing. How do I do boolean ORing.?</p>
