我的第一个猜测是在您的search.php 要更改的模板post_type 和posts_per_page

可能是这样的

<?php
$s = get_search_query();
$args_array = [
  {\'s\' =>$s,\'post_type\'=>\'products\',\'posts_per_page\'=>5},
  {\'s\' =>$s,\'post_type\'=>\'posts\',\'posts_per_page\'=>3},
  {\'s\' =>$s,\'post_type\'=>\'pages\',\'posts_per_page\'=>5},
],
foreach( $args_array as $args ) {
  $the_query = new WP_Query( $args );
  while ( $the_query->have_posts() ) : $the_query->the_post();
    // YOUR CODE HERE
  endwhile;
wp_reset_postdata();
