我对按自定义字段筛选帖子有问题。在我的页面上，我有一个包含15个条件（放射性核素和输入）的表单，我想用它们过滤我的自定义post-type项目。我的问题是，当我使用这么多元键时，查询速度非常慢。这是我的代码：

$posts = get_posts(array(
    \'numberposts\'   => -1,
    \'post_type\'     => \'projekt\',
    \'post_status\' => \'publish\',
    \'s\' => $s,
    \'meta_query\'    => 
         array(
        \'relation\'  => \'AND\',
         array(
        \'key\'       => \'technologia_wyszukiwarka\',
        \'value\'     => $techs,
        \'compare\'   => \'LIKE\'       
        ),
        array(
        \'key\'       => \'zabudowa_wyszukiwarka\',
        \'value\'     => $styls,
        \'compare\'   => \'LIKE\'
        ),
        array(
            \'key\'       => \'garaz_wyszukiwarka\',
            \'value\'     => $garazs,
            \'compare\'   => \'LIKE\'
        ),
        array(
            \'key\'       => \'mdm_wyszukiwarka\',
            \'value\'     => $mdms,
            \'compare\'   => \'LIKE\'
        ),
        array(
            \'key\'       => \'powierzchnia_wyszukiwarka\',
            \'value\'     => $pows,
            \'compare\'   => \'LIKE\'
        ),
        array(
            \'key\'       => \'kondygnacja_wyszukiwarka\',
            \'value\'     => $konds,
            \'compare\'   => \'LIKE\'
        ),
        array(
            \'key\'       => \'ogrzewanie_wyszukiwarka\',
            \'value\'     => $ogrzewanies,
            \'compare\'   => \'LIKE\'
        ),  
        array(
            \'key\'       => \'liczba_pokoi_wyszukiwarka\',
            \'value\'     => $pokojes,
            \'compare\'   => \'LIKE\'
        ),      
        array(
            \'key\'       => \'inne_wyszukiwarka\',
            \'value\'     => $innes,
            \'compare\'   => \'LIKE\'
        ),  
        array(
            \'key\'       => \'kat_dachu_wyszukiwarka\',
            \'value\'     => array($katods,$katdos),
            \'compare\'   => \'BETWEEN\',
            \'type\' => \'NUMERIC\'
        ),  

    ),
));

我的查询时间WP_Query->get_posts 大约是10秒。但当我删除最后的条件时kat_dachu_wyszukiwarka 时间更短，可以接受0.5秒，我用查询监视器进行了检查。不幸的是，我需要这个字段和几个字段。因此，我的问题是如何更快地执行查询？
