I figured this out so I am going to post it here for others..
backup the tickets.inc.php file:cp include/staff/tickets.inc.php /tmp/edit the file:nano include/staff/tickets.inc.phparound line 419 (on my version of the file) there is the following:<div class="attached input"> <input type="text" class="basic-search" data-url="ajax.php/tickets/lookup" name="query" autofocus size="30" value="<?php echo Format:($_REQUEST, true); ?>" autocomplete="off" autocorrect="off" autocapitalize="off"> <button type="submit" class="attached button"><i class="icon-search"></i> </button> </div>Removing the following section of text returned the search box to a standard search box without auto complete:data-url="ajax.php/tickets/lookup" name="query"
