大家帮忙看看这段代码问题在哪，关于全文检索的

public string indexpath = "F:\\index";

private void button1_Click(object sender, EventArgs e)
{
DialogResult result = folderBrowserDialog1.ShowDialog();
string path;
if (result == DialogResult.OK)
{
path = this.folderBrowserDialog1.SelectedPath;
IndexWriter writer = new IndexWriter(indexpath, new StandardAnalyzer(), true);
FileInfo file = new FileInfo(path);
IndexDirectory(writer,file);
writer.Optimize();
writer.Close();
}
}
public void IndexDirectory(IndexWriter writer, FileInfo file)
{

if (Directory.Exists(file.FullName))
{
String[] files = Directory.GetFileSystemEntries(file.FullName);

if (files != null)
{
for (int i = 0; i < files.Length; i++)
{
IndexDirectory(writer, new FileInfo(files[i])); //这里是一个递归
}
}
}
else if (file.Extension == ".txt")
{
IndexFile(file, writer);
}
}

public void IndexFile(FileInfo file,IndexWriter writer)
{
Document doc = new Document();
doc.Add(Field.Keyword("filename", file.FullName));
doc.Add(Field.Text("contents", new StreamReader(file.FullName, System.Text.Encoding.Default)));
writer.AddDocument(doc);
}

下面是搜索的。
private void button2_Click(object sender, EventArgs e)
{
IndexSearcher searcher = new IndexSearcher(indexpath);
Query query = QueryParser.Parse(this.textBox2.Text, "contents", new ChineseAnalyzer());
Hits hit = searcher.Search(query);
printResult(hit);
}
void printResult(Hits hit)
{
if (hit.Length() == 0)
{
MessageBox.Show("对不起，没有搜索到你要的结果。");
}
else
{
for (int i = 0; i < hit.Length(); i++)
{
try
{
Document doc = hit.Doc(i);
MessageBox.Show("这是第" + i + "个搜索结果,文件名为" + doc.Get("filename"));
}
catch (Exception ex)
{
MessageBox.Show("错误:"+ex.Message);
}
}
}
}

我的问题是：按照上面的代码只能检索英文的，数字都不行，中文有的能检索出来，有的检索不出来。

建索引采用的分词应该与查询时对查询条件进行分词的分词器应该一致才对...............(个人意见)

UP,可以单步跟踪一下。
