title: Stripe, is it possible to search a customer by their email?
body: <p><strong>Update:</strong> Since around January 2018, it is now possible to search using the  <code>email</code> parameter on Stripe. See the <a href="https://stackoverflow.com/a/48533693/330867">accepted answer</a>.</p>
  <hr />
  <p>I was wondering if it was possible to search a customer only by their email address when using the Stripe API.</p>
  <p>The <a href="https://stripe.com/docs/api#list_customers" rel="nofollow noreferrer">documentation</a> only indicates searching by:</p>
  <pre><code>created,
  ending_before,
  limit,
  starting_after 
  </code></pre>
  <p>But not <strong><code>email</code></strong>.</p>
  <p>I'd like to avoid having to list over all my customers to find which ones have the same email addresses.</p>
