WSS[sharepoint]中如何建立一个搜索的功能的webpart[Search]

with Windows sharepoint service, how to build a webpart to support search one list of a web site.

这个webpart的使用必须让MSSQL支持全文索引才行。
在sql客户端运行
sp_fulltext_database 'enable'

使用时要小心。如果已经存在全文目录,那么该过程将除去所有的全文目录,重新创建系统表中指明的任何全文索引,并且将数据库标记为已全文启用。

这个webpart例子是显示一个站点所有的list,并把每个list的field显示出来,同时根据输入查询的字符串来查询这个list的记录。
[如何创建webpart和如何加入webpart到wss中去这里就不介绍了。]
下面给完整代码
