lucene.net的搜索问题，谢谢指点。

我最近在研究用Lucene做网站搜索功能，遇到如下问题，代码如下

创建索引

private static void CreateIndex()
{
string path = @"d:\search\";
IndexWriter writer = new IndexWriter(path, new StandardAnalyzer(),true);
Document doc = new Document();
string strSQL = "SELECT TOP 100 title FROM Article ";
DataTable dt = SqlHelper.ExecuteDataTable(strSQL);
foreach (DataRow dr in dt.Rows)
{
doc.Add(new Field("title", dr["title"].ToString(), Field.Store.YES, Field.Index.TOKENIZED));
writer.AddDocument(doc);
}

writer.Optimize();
writer.Close();
}

搜索
private static void Search(string words)
{
string path = @"d:\search\";
IndexSearcher searcher = new IndexSearcher(path);
Query query = new QueryParser("title", new StandardAnalyzer()).Parse(words);
Hits hits = searcher.Search(query);
Console.WriteLine(hits.Length());
for (int i = 0; i < hits.Length(); i++)
{
Document doc = hits.Doc(i);
string title = doc.Get("title").ToString();
Console.WriteLine(title);
}
searcher.Close();
}

现在的问题是，我无论输入的什么关键词，都返回上面SQL查询的第一列的title
请问是哪里写错了，请指教。

从实例出发

创建索引
private static void CreateIndex()
{
string path = @"d:\search\";
IndexWriter writer = new IndexWriter(path, new StandardAnalyzer());
Document doc = new Document();

doc.Add(new Field("title", "AC米兰队", Field.Store.YES, Field.Index.TOKENIZED));
doc.Add(new Field("title", "曼彻斯特联队", Field.Store.YES, Field.Index.TOKENIZED));
doc.Add(new Field("title", "曼彻斯特城队", Field.Store.YES, Field.Index.TOKENIZED));
doc.Add(new Field("title", "国际米兰队", Field.Store.YES, Field.Index.TOKENIZED));
doc.Add(new Field("title", "尤文图斯队", Field.Store.YES, Field.Index.TOKENIZED));

writer.AddDocument(doc);
writer.Optimize();
writer.Close();
}

搜索
private static void Search(string words)
{
Console.WriteLine(words);
string path = @"d:\search\";
IndexSearcher searcher = new IndexSearcher(path);
Query query = new QueryParser("title", new StandardAnalyzer()).Parse(words);
Hits hits = searcher.Search(query);
Console.WriteLine(hits.Length());
for (int i = 0; i < hits.Length(); i++ )
System.Console.WriteLine(hits.Doc(i).GetField("title").StringValue());
searcher.Close();
}

现在我运行Search("城")
hits.Length() = 1；
只搜索出来了“AC米兰队”
请问是哪里出了问题，请指教，谢谢。
