本机搜索页面运行如下查询：

SELECT SQL_CALC_FOUND_ROWS  wp_posts.* 
FROM wp_posts 
WHERE 1=1 AND (((wp_posts.post_title LIKE \'%keyword%\') 
OR (wp_posts.post_content LIKE \'%keyword%\')) 
AND (wp_posts.post_password = \'\') 
AND wp_posts.post_type IN (\'post\', \'page\', \'attachment\') 
AND (wp_posts.post_status = \'publish\') 
ORDER BY wp_posts.post_date DESC LIMIT 0, 10

我通过挂接到pre\\u get\\u帖子来向查询传递特定的帖子ID，因此我不需要其他帖子WHERE 与关键字相关的条件。e、 g。

add_filter(\'pre_get_posts\',\'my_search_filter\');
function my_search_filter($query) {
    if ($query->is_search) {
            // post IDs within distance X
        $matches = array(1,3,5);
        $query->query_vars[\'post__in\'] = $matches;

    }
}

如何通过修改现有查询而不是编写新查询，从查询对象中删除与post\\u title和post\\u内容相关的条件。
