   Example function search by title only:

   function wpdocs_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', 'wpdocs_search_by_title_only', 500, 2 );

   • function __search_by_title_only( $search, &$wp_query ) Should be: function __search_by_title_only( $search, $wp_query )
