Search in Discuss to be replaced with Google custom search

Hello,

In file
...\components\com_easydiscuss\themes\wireframe\toolbar\default.php

there is a code for enabling search

<div class="ed-navbar__search">

		

		     <form class="ed-navbar__search-form" name="discuss-toolbar-search" data-search-toolbar-form method="post" action="<?php echo JRoute::_('index.php'); ?>">

    	        <input type="text" placeholder="<?php echo JText::_('COM_EASYDISCUSS_SEARCH_DEFAULT');?>" autocomplete="off" class="ed-navbar__search-input" data-search-input name="query" value="<?php echo ED::string()->escape($query); ?>">

                <input type="hidden" name="option" value="com_easydiscuss" />

                <input type="hidden" name="controller" value="search" />

                <input type="hidden" name="task" value="query" />

                <input type="hidden" name="Itemid" value="<?php echo DiscussRouter::getItemId('search'); ?>" />

                <?php echo JHTML::_( 'form.token' ); ?>

    	    </form>



    	</div>

Can the code can be replaced with Google custom search.
I mean - using custom search instead of above - can it impact discuss component functionlity in any way

Thanks
