哪位高手帮忙修改出站内搜索的搜索引擎

希望能够在狐狸里面添加站内搜索。

我看过相关的搜索引擎修改的帖子，可是不知道怎么做。

下面的资料不知道有没有参考价值：

mathon的google搜索引擎代码

Google站内搜索用于在当前浏览的站点范围内搜索指定关键字

引擎代码

<script language="JavaScript">var searchText = external.m2_search_text(%max_security_id);var root;var rooturl;getRoot();var URL="http://www.google.com/search?hl=zh-CN&ie=UTF-8&q=site:";+rooturl+"+"+encodeURIComponent(searchText);window.open(URL);function getRoot() {updir = location.href.substring(0,location.href.substring(0,location.href.length-1).lastIndexOf('/')+1);updir2 = location.href.substring(location.href.substring(0,location.href.length-1).lastIndexOf('http://'),location.href.length);updir2 = updir2.substring(7,location.href.length);if (updir.indexOf("htm#http") != -1 && updir2.indexOf("www") == 0 ){root="http://";+updir2;};if (updir.indexOf("htm#http") != -1 && updir2.indexOf("www") != 0 ){root="http://www.";+updir2;};root=window.location.href.split("/");rooturl=root[2];};</script>
</script>

这是 baidu 的站内搜索代码

<script language="JavaScript">var searchText = external.m2_search_text(%max_security_id);var root;var rooturl;getRoot();var URL="http://www.baidu.com/s?ie=UTF-8&ct=0&cl=3&f=8&bs=site%3Awww.f1suji.com+%C4%E3%BA%C3&sr=&z=&wd=site:";+rooturl+"+"+encodeURIComponent(searchText);window.open(URL);function getRoot() {updir = location.href.substring(0,location.href.substring(0,location.href.length-1).lastIndexOf('/')+1);updir2 = location.href.substring(location.href.substring(0,location.href.length-1).lastIndexOf('http://'),location.href.length);updir2 = updir2.substring(7,location.href.length);if (updir.indexOf("htm#http") != -1 && updir2.indexOf("www") == 0 ){root="http://";+updir2;};if (updir.indexOf("htm#http") != -1 && updir2.indexOf("www") != 0 ){root="http://www.";+updir2;};root=window.location.href.split("/");rooturl=root[2];};</script>

希望狐狸高手能尽快研究出这个功能，造福所有狐狸
