Lucene起步

1.创建Lucene索引
IndexWriter writer=new IndexWriter(indexDir,new StandardAnalyzer(),true);
writer.setUseCompoundFile(false);

2.索引文件的内容
Document doc=new Document();
doc.add(Field.Text("contents",new FileReader(f)));

3.索引文件名
doc.add(Fileld.Keyword("filename",f.getCanonicalPath()));

4.将Document对象添加到Lucene的索引中去
writer.addDocument(doc);
