title: Github: Find PRs where user is a reviewer
body: <p>Github added <a href="https://github.com/blog/2291-introducing-review-requests" rel="noreferrer">reviewers</a>.</p>
  
  <p>Is there a way to find PRs (e.g. on the <a href="https://github.com/pulls" rel="noreferrer">Pull Requests</a> page) where the user is a reviewer? Things I have already tried:</p>
  
  <ul>
  <li><p>Checked <a href="https://help.github.com/articles/searching-issues/" rel="noreferrer">https://help.github.com/articles/searching-issues/</a> for a filter: </p>
  
  <p>None found</p></li>
  <li><p>Tested potential filters reviewer:{{user}}, review:{{user}}</p>
  
  <p>No PRs returned</p></li>
  <li><p>Tested the involved:{{user}} filter</p>
  
  <p>PRs with the user as only a reviewer are not shown in results.</p></li>
  </ul>
