我有这个查询，当我减少过滤器时它变得很快，但是当我增加过滤器时它变得太慢，请我需要使用所有这些过滤器使其快速。由于我的详细信息很清楚，但我正在写一些行，因为它不允许我发布我的问题

$args = array('post_type' => 'property', 'posts_per_page' => 1,'order' => 'asc',

【问题讨论】：

不幸的是，我没有看到在一个查询中进行这么多 LIKE 比较的情况可能会很快。根据您正在搜索的数据集的大小，您可能希望为用户提供一组预定义的选项，用于大多数输入，然后使用 = 比较而不是 LIKE。
感谢您的评论，那么我应该用什么来代替“LIKE”？
而不是LIKE，只需使用=。我认为state、hospitaltype 和facilitytype 绝对可以切换到那个，除非你让人们搜索isconsi 或其他东西。您还可以从$wp_query 获取实际的 SQL 查询，并尝试使用manually optimize it 或保存数据的表
请提供（1）生成的SQL，和（2）SHOW CREATE TABLE。

终于找到了解决办法，在这里分享给和我一样可能有同样问题的人

$meta_query = array();
    $args = array();
    $args = array('posts_per_page' => -1,);
    $meta_query[] = array(
        'key' => 'facilityname',
        'value' => $_GET['keyword'],
        'compare' => 'LIKE'
    );
    $meta_query[] = array(
        'key' => 'city',
        'value' => $_GET['city'],
        'compare' => 'LIKE'
    );
    $meta_query[] = array(
        'key' => 'facilitytype',
        'value' => $_GET['facilitytype'],
        'compare' => 'LIKE'
    );
    $meta_query[] = array(
        'key' => 'hospitaltype',
        'value' => $_GET['hospitaltype'],
        'compare' => 'LIKE'
    );
    $meta_query[] = array(
        'key' => 'state',
        'value' => $_GET['state'],
        'compare' => 'LIKE'
    );
    $meta_query[] = array(
        'key' => 'idn',
        'value' => $_GET['idn'],
        'compare' => 'LIKE'
    );
    $meta_query[] = array(
        'key' => 'gpoaffiliations',
        'value' => $_GET['gpoaffiliations'],
        'compare' => 'LIKE'
    );
    $meta_query[] = array(
        'key' => 'bedcounttotal',
        'value'     =>  array($_GET['min-bedcounttotal'], $_GET['max-bedcounttotal']),
        'compare'   => 'BETWEEN',
        'type' => 'NUMERIC'
    );
    $meta_query[] = array(
        'key' => 'zipcode',
        'value'     =>  array($_GET['minzipcode'], $_GET['maxzipcode']),
        'compare'   => 'BETWEEN',
        'type' => 'NUMERIC'
    );
    $meta_query[] = array(
        'key' => 'operatingroomcount',
        'value'     =>  array($_GET['minoperatingroomcount'], $_GET['maxoperatingroomcount']),
        'compare'   => 'BETWEEN',
        'type' => 'NUMERIC'
    );
    //if there is more than one meta query 'or' them
    if(count($meta_query) > 1) {
        $meta_query['relation'] = 'AND';
    }
    
    // The Query
    $args['post_type'] = "property";
    $args['meta_query'] = $meta_query;
