Good idea. This prints jobs sorted:

    function hideAllExcept(searchRegex) {
        var allComments = Array.from(document.querySelectorAll('.comment-tree .comtr'))
            .map(function(e){e.style.display='none';return e});
        var topLevelComments = allComments.filter(e=> e.querySelector('img[width="0"]'));
        var matchedComments = topLevelComments.filter(e=> 
            (e.style.display = searchRegex.test(e.querySelector('.comment').innerText) ? 'table-row' : 'none')=='table-row');
        return 'Showing '+(matchedComments.length+'').padStart(3, ' ')+' out of '+topLevelComments.length+' jobs for '+searchRegex;
    }
