        private static void AddDocument(IndexWriter writer, FileInfo filename)
        {
            Document doc = new Document();
            doc.Add(new Field("filename", filename.Name, Field.Store.YES, Field.Index.TOKENIZED));
            doc.Add(new Field("contents", new StreamReader(filename.FullName)));
            writer.AddDocument(doc);
        }

为 什么这样做我的contents字段是空的?
