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 );
