我正在进行搜索。我可以按标签和类别搜索帖子，但不能按标题和内容搜索。

我尝试了下面的代码，但不起作用。你能帮帮我吗？

$getSearch = get_search_query();
//print($search);
$query = new WP_Query([
  \'post_type\' => \'post\',
  \'tax_query\' => array(
    \'relation\' => \'OR\',
       array(
      \'s\'=> $getSearch // for title and content
    ),
    array(
      \'taxonomy\' => \'post_tag\', //for tag
      \'field\' => \'slug\',
      \'terms\' => array($getSearch),
    ),
    array(
      \'taxonomy\' => \'category\', // for category
      \'field\' => \'slug\',
      \'terms\' => array($getSearch),
    ),
  ),
]); 

if ($query->have_posts() ):
      while ( $query->have_posts() ) {$query->the_post();?>
<!--some content-->
<?php }
else :
       get_template_part( \'template-parts/content\', \'none\' );
        endif;
?>

function.php

add_action( \'pre_get_posts\', \'my_search_exclude\' );
function my_search_exclude( $query ) {
  if ( ! $query->is_admin && $query->is_search && $query->is_main_query() ) {
    $query->set( \'post_type\', array( \'post\', \'page\', \'product\' ) );
    $query->set( \'post__not_in\', array( 471 ) );
     $taxquery=  array(
  \'post_type\' => \'any\',
  \'s\'=> $query->get(\'s\')
);
$query->set( \'tax_query\', $taxquery);

  }
}
