title: aws identity pool filter list users api on multiple conditions
body: <p>Is there a way to filter the result from list users api on multiple conditions. I want to get list of all users who have usernames from a list</p>
  
  <pre><code>import boto3
  client = boto3.client('cognito-idp')
  client.list_users(UserPoolId='us-east-1_123456789', AttributesToGet=['email'], Filter="username =\"user_name_1\"")
  </code></pre>
  
  <p>the above code returns me only one username. Now if I want to get the same information for multiple usernames I cant seem to find a way to do it.</p>
  
  <p>ex:</p>
  
  <pre><code>import boto3
  usernames=['user_id1','user_id2']
  client = boto3.client('cognito-idp')
  client.list_users(UserPoolId='us-east-1_123456789', AttributesToGet=['email'], Filter="username =usernames")
  </code></pre>
