Question

我的网站是 woocommerce 网站。我的问题是搜索框。每次我使用SKU搜索时都没有结果。它仅在我搜索帖子，产品和页面结果时显示结果。它没有显示woocommerce SKU产品。

如何修复此WordPress搜索结果？

这是我的WordPress search.php

<?php get_header(); ?>

     if($s){    
     $where = ' title  LIKE \'%' . esc_sql( like_escape($s) ) . '%\'';

     $arr_title = explode(' ',$s);
     foreach($arr_title as $search_term):   
       $where .= ' OR title LIKE \'%' . esc_sql( like_escape( $search_term ) ) . '%\'';
     endforeach;


     $query = "
