title: Jenkins job filter regular expression just doesn't work
body: <p>My Jenkins version is 2.7.8, I have job like Email_AAA Email_BBB Email_CCC etc
  i created a view and set the filter with following Regular Expression：
  ^Email.*$</p>
  
  <p>But nothing is returned
  I didn't find anything related to this in log.
  Any possible clues?</p>
