FTS使用故障

我通过这个创建了一个FTS article 我有一个varbinary(max)类型的列,我用MSWord文件(.doc)填充了它,还有一个word类型的列(用.doc填充)。 运行此脚本时,输出为空

SELECT 
    name,
    content
FROM tblWordFiles 
WHERE FREETEXT(content, '1');

或

SELECT 
    name,
    content
FROM tblWordFiles 
WHERE contains(content, '1');

噢噢噢! 我用这段代码填充数据库(c)

    SqlConnection cn = new SqlConnection(@"Data Source=MJ;Initial Catalog=Test_word_binary;Integrated Security=True");
    string command = "insert into tblWordFiles (type,content) values('doc','@c')";
    SqlCommand cm = new SqlCommand(command, cn);
    DialogResult dg = openFileDialog1.ShowDialog();
    if (dg == DialogResult.OK)
    {
        // Create a new stream to load this photo into
        System.IO.FileStream stream = new System.IO.FileStream(openFileDialog1.FileNames[0], System.IO.FileMode.Open, System.IO.FileAccess.Read);
        // Create a buffer to hold the stream bytes
        byte[] buffer = new byte[stream.Length];
        // Read the bytes from this stream
        stream.Read(buffer, 0, (int)stream.Length);
        // Now we can close the stream
        stream.Close();

        cm.Parameters.Add("@c", SqlDbType.VarBinary).Value = buffer;
        cn.Open();
        cm.ExecuteNonQuery();
        cn.Close();
    }
