title: find all requests in which user is participant in the service desk
body: <p>In JIRA, how to get the all issues which user is participant?
  I can get the results for assignee and reporter. </p>
  
  <p>I am using following query to get the issues when the user is reporter.</p>
  
  <blockquote>
    <p>reporter = user AND updated > -10d</p>
  </blockquote>
  
  <p>I need to display the issues only the user is participant not the reporter or assignee. How to achieve this in the search API?</p>
