Finding Folks Who Did Not Open an Email

[Shai]

In CiviMail Reports, it is easy enough to find folks who opened an email.  From "Scheduled and Sent" page, click on "Report" for the mailing you are interested in. It takes one to:

/civicrm/contact/search/advanced?force=1&mailing_id=<mailing id>&mailing_open_status=Y

Nowhere on that search form can I find a setting to change the mailing_open_status from "Yes" to "No." Certainly it is easy enough to do that directly in the URL. But the page is confusing because criteria are listed right at the top of the results and yet the form above doesn't provide any opportunity to change those specific criteria.

Am I missing something? Can one directly set Mailing Open Status directly from the form?
