lucene3.0中的RAMDirectory 和FSDirectory

Posted 2023-03-14

JAVA 中如何实现这两个的转换 与使用

参考技术A RAMDirectory ramDir=new RAMDirectory();
FSDirectory fsDir= FSDirectory.open(new File(index_path));

IndexWriter ramWriter=new IndexWriter(ramDir,new MMAnalyzer(),true, IndexWriter.MaxFieldLength.LIMITED);
IndexWriter fsWriter=new IndexWriter(fsDir,new MMAnalyzer(),true, IndexWriter.MaxFieldLength.LIMITED);

Document doc=new Document();

Fieldfield=new Field("id","id"Field.Store.YES,Field.Index.NOT_ANALYZED);
doc.add(id_field);
……

ramWriter.addDocument(doc);
ramWriter.close();

fsWriter.addIndexes(new Directory[] ramDir);
fsWriter.close();
大概是这样
