In Google Analytics > User Explorer > Search For User
<p>I am simply trying to search for a certain user based on their <code>Client Id</code>.  How Can I find a particular user like <code>129237576.1471287532</code> to view their 
<code>User Report</code>.</p>

<p>Secondly... how could I search all users for a pattern.  So instead of numbers.numbers - search numbers_numbers - so 129237576.1471287532 vs. 14756_7856.</p>
