关于Lucene搜索不到结果问题!!这是一个入门的小栗子...我被难住了..求指点迷津

[qq_21369103]

实在是不知道要发在那个版块了!!

出现的问题:我想要搜索fileContent力的内容!但是却搜不到文档对象......
topDocs长度为0

首先是创建索引!

public void createIndex()
    {
        boolean create = true;
        Directory directory = null;
        IndexWriter indexWriter = null;
        try
        {
            File fold = new File("e:\\TEMP\\lucene\\db");
            //            //1.创建目录
            //            directory = new SimpleFSDirectory(fold);
            directory = FSDirectory.open(fold);

            //2.创建索引
                /*2.2*/
            Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_35);
                 /*2.1*/
            IndexWriterConfig indexWriterConfig = new IndexWriterConfig(Version.LUCENE_35, analyzer);
            if (create)
            {
                indexWriterConfig.setOpenMode(IndexWriterConfig.OpenMode.CREATE);
            } else
            {
                indexWriterConfig.setOpenMode(IndexWriterConfig.OpenMode.CREATE_OR_APPEND);
            }
                /*2.0*/
            indexWriter = new IndexWriter(directory, indexWriterConfig);
            //3.创建Document
            Document document = null;

            File file = new File("E:\\TEMP\\Lucene");

            for (File txtFile : file.listFiles())
            {
                if (txtFile.isFile())
                {
                    //4.为Document 添加Field
                    document = new Document();
                    document.add(new Field("fileName", txtFile.getName(), Field.Store.YES, Field.Index.NOT_ANALYZED));
                    document.add(new Field("filePath", txtFile.getAbsolutePath(), Field.Store.YES, Field.Index.NOT_ANALYZED));
                    document.add(new Field("fileContent", new BufferedReader(new FileReader(txtFile))));
                }
            }
            //5.通过IndexWriter 添加到文档索引中
            indexWriter.addDocument(document);
        } catch (IOException e)
        {
            e.printStackTrace();
        } finally
        {
            try
            {
                if (indexWriter != null)
                {
                    indexWriter.close();
                }

                if (directory != null)
                {
                    directory.close();
                }
            } catch (IOException e)
            {
                e.printStackTrace();
            }
        }


    }

    public void searcher()
    {
        Directory d = null;
        IndexReader ir = null;
        IndexSearcher is = null;
        OutputStreamWriter osw = null;

        try
        {
            //1.创建Directory
            d = FSDirectory.open(new File("e:\\TEMP\\lucene\\db"));

            //2.创建IndexReader
            ir = IndexReader.open(d);

            //3.根据IndexReader 创建 IndexSearcher
            is = new IndexSearcher(ir);
            //3.创建搜索对象 Query
            StandardAnalyzer sdr = new StandardAnalyzer(Version.LUCENE_35);
            QueryParser qp = new QueryParser(Version.LUCENE_35, "fileName", sdr);
            Query qr = qp.parse("t");
            //4.根据serarch并且返回TopDocs
            TopDocs topDocs = is.search(qr, 10);
            ScoreDoc[] scoreDocs = topDocs.scoreDocs;
            System.out.println("文档数:" + scoreDocs.length);
            //5.遍历TopDocs
            osw = new OutputStreamWriter(System.out);
            //            for (ScoreDoc sd : scoreDocs)
            //            {
            //                //5.1得到该document对象
            //                Document doc = is.doc(sd.doc);
            //                List<Fieldable> fieldableList = doc.getFields();
            //                for (Iterator<Fieldable> iterator = fieldableList.iterator(); iterator.hasNext(); )
            //                {
            //                    Fieldable next =  iterator.next();
            //                    Reader reader = next.readerValue();
            //                    //6.获取所要的值
            //                    char[] cbf = new char[1024];
            //                    while(reader.read(cbf) > 0)
            //                    {
            //                        osw.write(cbf);
            //                        System.out.println(1);
            //                    }
            //                }
            //            }
            //请忽略掉以上注释部分
            //6.获取所要的值

        } catch (Exception e)
        {
            e.printStackTrace();
        } finally
        {
            //7.关闭Reader流
            try
            {
                if (osw != null)
                {
                    osw.close();
                }

                if (is != null)
                {
                    is.close();
                }

                if (ir != null)
                {
                    ir.close();
                }
                if (d != null) {
                    d.close();
                }
            } catch (IOException e)
            {
                System.out.println(e.toString());
            }
        }

    }
}

然后是搜索

    public void searcher()
    {
        Directory d = null;
        IndexReader ir = null;
        IndexSearcher is = null;
        OutputStreamWriter osw = null;

        try
        {
            //1.创建Directory
            d = FSDirectory.open(new File("e:\\TEMP\\lucene\\db"));

            //2.创建IndexReader
            ir = IndexReader.open(d);

            //3.根据IndexReader 创建 IndexSearcher
            is = new IndexSearcher(ir);
            //3.创建搜索对象 Query
            StandardAnalyzer sdr = new StandardAnalyzer(Version.LUCENE_35);
            QueryParser qp = new QueryParser(Version.LUCENE_35, "fileName", sdr);
            Query qr = qp.parse("t");
            //4.根据serarch并且返回TopDocs
            TopDocs topDocs = is.search(qr, 10);
            ScoreDoc[] scoreDocs = topDocs.scoreDocs;
            System.out.println("文档数:" + scoreDocs.length);
           //........
} catch (Exception e)
        {
            e.printStackTrace();
        } finally
        {
            //7.关闭流
            try
            {
                if (osw != null)
                {
                    osw.close();
                }

                if (is != null)
                {
                    is.close();
                }

                if (ir != null)
                {
                    ir.close();
                }
                if (d != null) {
                    d.close();
                }
            } catch (IOException e)
            {
                System.out.println(e.toString());
            }
        }

    }
}

出现的问题:我想要搜索fileContent力的内容!但是却搜不到文档对象......
topDocs长度为0

最后我向请问的是,我写的这个代码是哪里出错了呢?
关于Lucene实在是了解的太少了!!

我只想从fileContent里查询到想要的结果!!!!
但是在视频里的老师确实是可以查询到的!!!
琢磨了好几小时没效果,现在发帖求助..
如果你可以帮助到我,且有闲暇时间,我下方提供了我现在学习Lucene的资源:
