title: How can I retrieve list members using given a unique_email_id on Mailchimp API v3?
body: <p>Given a <code>unique_email_id</code>, how can I retrieve all list members matching that ID?</p>
  
  <p>I am attempting to use the <code>search-members</code> endpoint, ala what I do for searching email-addresses:</p>
  
  <pre><code>https://us9.api.mailchimp.com/3.0/search-members?query=chris@chris.com
  </code></pre>
  
  <p>but instead (given a unique_email_id of 4dce5</p>
  
  <pre><code>https://us9.api.mailchimp.com/3.0/search-members?query=4dce5
  </code></pre>
  
  <p>and I'm getting no results.</p>
  
  <p>Is there another endpoint I'm missing?</p>
