How to exclude empty pages from WordPress Search Results

Pages with no content can appear in search results. To address this issue, I used the ‘pre_get_posts’ function to exclude any ‘post’ with an empty ‘post_content’ field from the search query.

Here’s the code I used:

	<?php
	/**
	* Exclude posts with empty post_content from search results
	*/
	function modify_search_query( $query ) {
	// Check if this is a search query and not an admin query
	if ( $query->is_search() && ! is_admin() ) {
	// Add a filter to exclude posts with empty post_content
	add_filter( 'posts_where', 'exclude_empty_post_content' );

	// Remove the filter after the search query has been modified
	add_action( 'wp', function() {
	remove_filter( 'posts_where', 'exclude_empty_post_content' );
	} );
	}
	}

	function exclude_empty_post_content( $where ) {
	global $wpdb;

	// Add a condition to exclude posts with empty post_content
	$where .= " AND ({$wpdb->prefix}posts.post_content != '')";

	return $where;
	}

	add_action( 'pre_get_posts', 'modify_search_query' );
