title: How to give multiple lookup-attributes while querying cloudtrail events
body: <p>Is it possible to query cloudtrail with multiple lookup attributes</p>
  
  <p>When I execute following </p>
  
  <pre><code>aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=CreateTopic 
  </code></pre>
  
  <p>It gives me list of events of type 'CreateTopic'</p>
  
  <p>When I execute following </p>
  
  <pre><code>aws cloudtrail lookup-events --lookup-attributes AttributeKey=AttributeKey=Username,AttributeValue=MyUserName 
  </code></pre>
  
  <p>It gives me list of events related to user 'MyUserName'</p>
  
  <p>However what I want is to query for all events of type 'CreateTopic' and related to user 'MyUserName'</p>
  
  <p>I tried following but none of them works</p>
  
  <pre><code>aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=CreateTopic,AttributeKey=Username,AttributeValue=MyUserName 
  aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=CreateTopic AttributeKey=Username,AttributeValue=MyUserName 
  aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=CreateTopic --lookup-attributes AttributeKey=Username,AttributeValue=MyUserName 
  </code></pre>
