lucene入門簡單的例子

import org.apache.lucene.util.Version;

public class LuceneTest {

public static void main(String[] args) throws IOException {

String ids[]={"1","2","3！"};

String context[]={"我是一個大菜鳥","你是一個好的程勳員","他是一個人人都愛的大美女！"};

String filePath="D://test/index";

//檔案存放位置

Directory directory=FSDirectory.open(new File(filePath));

//索引寫入配置類

IndexWriterConfig config=new IndexWriterConfig(Version.LUCENE_42, new StandardAnalyzer(Version.LUCENE_42));

IndexWriter indexWriter=new IndexWriter(directory, config);

for(int i=0;i<context.length;i++){

//建立文檔

Document document =new Document();

//stringfiele隻會索引但不會分詞

document.add(new StringField("id", ids[i], Store.YES));

//TextField既有索引又會分詞

document.add(new TextField("cont", context[i], Store.YES));

//為文檔寫入索引

indexWriter.addDocument(document);

}

 indexWriter.close();  

 System.out.println("資料初始化成功！");

//接下來做查詢

Directory dire=FSDirectory.open(new File(filePath));

IndexReader reader=DirectoryReader.open(dire);

IndexSearcher searcher=new IndexSearcher(reader);

//詞（cont是标，’一‘是内容） 

Term term=new Term("cont", "一");

//查詢這個詞

TermQuery query=new TermQuery(term);

//查詢前5條資料

TopDocs topDocs=searcher.search(query, 5);

System.out.println(topDocs.totalHits);

reader.close();

}

}
