Bolding search strings
In a search results page excerpts of blog posts that match search criterion are shown by default. If you would like to instead display portions of text that has the search strings with the strings bolded, it can be done by using Search Exceprt plugin. After activating that plugin, copy search.php from parent Builder theme into your active child theme and edit it.
replace
<?php the_title(); ?>
with
<?php echo $title; ?>
and add the following above it
<?php
$title = get_the_title();
$keys= explode(" ",$s);
$title = preg_replace('/('.implode('|', $keys) .')/iu',
'<strong class="search-excerpt">\0</strong>',
$title);
?>
