Hi bdbrown, could you please introduce some plugins that provide that functionality? Do you think that the child theme is good for me in my situation?
Thanks.

my searchpage.php:

<?php
		$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
		$district = $_GET['district']; //get the district from form
		$args = array(
			'post_status' => 'publish',
			'paged' => $paged ,
			'posts_per_page' => '12',
			'relation' => 'AND',
			'meta_query' => array(
				array(
					'key' => '_description_value',
					'value' => $district,
					'compare' => 'LIKE'
				)
			)
		 );
		$query = new WP_Query( $args );	?>
	<?php if ( !($query->have_posts()) ) : ?>
             --------do nothing-------
	<?php else : ?>
	<?php while ( $query->have_posts() ) : $query->the_post(); ?>
          --------loop-------
	<?php endwhile;?>
	<?php wp_reset_postdata();?>
<?php endif; ?>

I think the $query is null, it should do nothing. But it got 6 IDs in array[27], that confused me a lot.
