WordPress 默认的搜索功能还真挺弱的,搜索出来的结果很不符合人意,如果你想让它检索出来的结果更加相关,可以限定只搜索文章的标题,将下面的代码添加到主题的 functions.php 文件即可:
/**
* 让 WordPress 只搜索文章的标题
* https://www.wpdaxue.com/search-by-title-only.html
*/
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( like_escape( $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 );
