Conner 查找的问题我解决了

用下面的内容替代modules里的对应内容，如果不行你可能需要把所有数据导出来然后修改database.sql,给每个table都加上UTF-8字符集的标识，然后重新创建数据库，把数据dump回去就行了。也许根本就不需要这么做。如果一定要这么做，千万记得把数据dump好了，丢了我就杀了你，哈哈！！！你可以到http://jackey.no-ip.org/drupal上测试(输入关键字“我的妈”)。

node.module:
$find = do_search(array("keys" => $keys, "type" => "node", "select" => "SELECT n.nid AS lno, n.title AS title, n.created AS created, u.uid AS uid, u.name AS name, 1 AS count FROM node n LEFT JOIN users u ON n.uid = u.uid WHERE ( n.title LIKE BINARY '%' OR n.teaser LIKE BINARY '%' OR n.body LIKE BINARY '%') AND n.status = 1"));

comment.module:
$find = do_search(array("keys" => $keys, "type" => "comment", "select" => "SELECT c.cid as lno, c.nid as nid, c.subject as title, c.timestamp AS created, u.uid AS uid, u.name AS name, 1 AS count FROM comments c LEFT JOIN users u ON c.uid = u.uid WHERE (c.comment LIKE BINARY '%') AND c.status = 0;"));

project.module:
$find = do_search(array("keys" => $keys, "type" => "node", "select" => "SELECT n.nid AS lno, n.title AS title, n.created AS created, u.uid AS uid, u.name AS name, 1 AS count FROM node n LEFT JOIN users u ON n.uid = u.uid WHERE ( n.title LIKE BINARY '%' OR n.teaser LIKE BINARY '%' OR n.body LIKE BINARY '%') AND n.type = 'project_project' AND n.status = 1"));
