Hi there,
Unfortunately, there is no available settings to change that. To change that it requires some customization on the codes.
I'll help you once, checkout this file: /components/com_easysocial/themes/wireframe/search/default/default.php on line: 26, you'll need to pass `type` parameter to the search router.
<div class="es-search-advance">
<a href="<?php echo ESR::search(array('layout' => 'advanced', 'type' => 'page')); ?>"><?php echo JText::_('COM_EASYSOCIAL_ADVANCED_SEARCH_LINK'); ?></a>
</div>
Please do understand this is a customization on the core file and it will get overwritten when updating EasySocial. Therefore, I'd like to advise you to place your customization on the template override. Checkout our documentation on template override:

Hope this helps.
