How to Display Search Results After a Specific Date in WordPress

To display search results after a specific date in WordPress, you can customize your theme's search query using the "pre_get_posts" action hook. This approach guarantees the display of only posts published after the specified date in the search results.

To filter search results after the specified date, add the following code to the functions.php file of your theme:

function themesdna_filter_search_results_by_date( $query ) {
    if( $query->is_main_query() && ! is_admin() && $query->is_search() ) {
        // Set the date to filter results after
        $after_date = '2022-04-20';

        $date_query = array(
            array(
                'after' => $after_date,
                'inclusive' => true, // Include posts published on the specified date
            ),
        );

        $query->set('date_query', $date_query);
    }
}
add_action( 'pre_get_posts', 'themesdna_filter_search_results_by_date' );

Note: Remember to replace "2022-04-20" with your desired date.
