Lucene学习笔记一

1、创建Directory的方式

 

    //使用内存保存索引

     Directory dir = new RAMDirectiroy();

   //或者使用磁盘保存索引

    Directory  dir = FSDirectory.open(new File ("c://indexSource"));

 

2、创建IndexWriter

     创建IdnexWriter需要2个参数：Directory和IndexWriterConfig.而创建创建IndexWriterConfig需要Analyzer和Lucene版本号。

       Directory dir = FSDirectory.open(indexFile);
       Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_36);
       IndexWriterConfig writerConf = new IndexWriterConfig(Version.LUCENE_36, analyzer);
       // 创建IndexWriter
       writer = new IndexWriter(dir, writerConf);
