如何只在wordpress中搜索帖子和页面标题？

I want to search according page and post title only. is it possible? my search code in header file is below

<form method="get" class="search-form" action="<?php echo esc_url( home_url( '/' ) ); ?>">
    <input type="search" class="form-control" placeholder="<?php esc_attr_e( 'Search...', 'consulting' ); ?>" value="<?php echo esc_attr( get_search_query() ); ?>" name="s" /></div>
    <button type="submit" style="height:7.5vh;"><i class="fa fa-search"></i></button>
</form>

You can search in post and page titles by adding below code to functions.php:

function __search_by_title_only( $search, &$wp_query )
{
   global $wpdb;
   if(empty($search)) {
      return $search; // skip processing - no search term in query
   }
   $q = $wp_query->query_vars;
   $n = !empty($q['exact']) ? '' : '%';
   $search =  ''; // this must be empty first
   $searchand = '';
   foreach ((array)$q['search_terms'] as $term) {
       $term = esc_sql($wpdb->esc_like($term));
       $search .= "{$searchand}($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";
       $searchand = ' AND ';
   }
   if (!empty($search)) {
      $search = " AND ({$search}) ";
      if (!is_user_logged_in())
         $search .= " AND ($wpdb->posts.post_password = '') ";
   }
   return $search;
}
add_filter('posts_search', '__search_by_title_only', 500, 2);

function __search_by_title_only( $search,  &$wp_query ){

  global $wpdb;

  if(empty($search)) {

     return $search; // skip processing - no search term in query

  }

  $q = $wp_query->query_vars;

  $n = !empty($q['exact']) ? '' : '%';

  $search = '';

  $searchand = '';

  foreach ((array)$q['search_terms'] as $term) {

     $term = esc_sql($wpdb->esc_like($term));

     $search .= "{$searchand}($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";

     $searchand = ' AND ';

 }

  if (!empty($search)) {

     $search = " AND ({$search}) ";

     if (!is_user_logged_in())
         $search .= " AND ($wpdb->posts.post_password = '') ";

 }

    return $search;

 }

    add_filter('posts_search', '__search_by_title_only', 500, 2);

Add this code in your theme functions.php file

in search.php use below query to override default search functionality or you can use custom template

$args = array(
            'post_type' => 'post',
            's' => $keyword,
            'cat' => $catSearchID,
            'tag'   => $tag-slug,
            'posts_per_page' => -1,
            'location' => $post_location_search ,
        );

$wp_query = new WP_Query($args);
