body: <p>I try to filter for log messages by https:// endpoints such as <code>https://test.com</code> to find request/response to external systems in Kibana Discover.</p>
  
  <p>When trying to escape the special characters <code>message: https\:\/\</code>. I get the following error:</p>
  
  <p><code>Discover: Expected "*", "\", "\n", "\r", "\t", [\ \t\r\n] or end of input but ":" found.</code></p>
