title: How do I search GitHub issues "created in the last seven days"?
body: <p>We'd like to list all GitHub issues created in the last seven (or, <em>n</em>) days. This is a relative time window.</p>
  
  <p>We don't want to use a specific date, because we'd like to create a link that is always correct (so we can link to the report of recent issues).</p>
  
  <p>Thanks!</p>
