我不知道有哪些现成的函数支持这一点，但您可以轻松构建WP_Term_Query 这样做。以下代码未经测试，但应能正常工作：

$args = [
    \'description__like\' => \'the description you\\\'re searching for\',
    \'taxonomy\'          => \'category\',//or other taxonomy
    \'fields\'            => \'ids\',
    \'hide_empty\'        => false,
];
$term_query = new WP_Term_Query($args);
foreach ($term_query->terms as $term) {
    // ID is in $term->term_id
}
