Drupal中文搜索问题解决办法

中文搜索问题解决办法

1. 把 search 模块修改一下。

drupal中不能搜索中文的原因是因为drupal不能判断中文的词语，所以中文字联在一起的时候就会看成是一个词，导致不能搜索。

解决的方法就是在搜索的词汇前后默认加上*号，让drupal搜索“含有”搜索汉字的词语，这样就可以了。

具体方法：
在search.modules里查找：
$keys = str_replace("*", "%", $keys);

把它变成
$keys = '%'.str_replace("*", "%", $keys).'%';
就可以了。

2. 修改各个模块的 do_search 函数

用下面的内容替代modules里的对应内容：

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;"));
