title: JQL: How do I search for JIRA issues that link to URLs with a certain pattern?
body: <p>In Jira, we use regular Web Links to point to an independent issue tracking system (for customer support). Those links can easily be identified by their domain name or URL prefix, e.g., they all have this form:</p>
  
  <pre><code>http://support.mycompany.com/ticket#1234
  </code></pre>
  
  <p>How can I filter for Jira issues that have links to URLs following this pattern?</p>
  
  <p>The JQL editor does not offer anything related to issue links, and "link" and "URL" are genuinely bad search terms.</p>
